18-Dec-17
Marco Ciapetti

2. Introduction Problems of the existing ceiling
Taken decisions for electrical and IT matters
Various updates
Current status of the project
Updated schedule
Things to be decided

3. Problems of the ceiling
During ARCECLIMA works performed on the existing ceiling, some panels have been badly damaged under the weight of the people
TC has put in place the following temporary solution:
A temporary reinforcement to secure the material lobby ceiling
A temporary scaffolding to grant a safe access to the ceiling
A temporary reinforcement to secure the radiation lab ceiling
TC has clearly highlighted the safe area of the ceiling that can be accessed
The access to the CV duct where ARCECLIMA need to work is now accessible
TC and SMB are working to find a permanent solution (see next slide)

4. Reinforcement of the ceiling proposal

5. Sockets plate ACCEPTED
It has been agreed to add all the sockets (Electrical and IT) on a custom plate. This will allow to have one single hole in the wall/enclosure for each spot. The custom plate has been designed by EN-EL and TC and accepted by the users. The agreed height of the plate from the floor is 500mm (center). A preliminary draft is shown below. Dimensions will be confirmed ASAP.
ACCEPTED

6. Sockets plates and switches

7. with the supervision of TC
Various updates
Due to the ceiling problems the access to the ceiling is currently RESTRICTED to the highlighted areas.
NOT ACCESSIBLE AREAS!
Now accessible BUT
with the supervision of TC
The radiation lab ceiling has been reinforced as well. The CV duct now reachable, but it can be accessed ONLY WITH THE SUPERVISION OF TC  ARCECLIMA must contact me BEFORE accessing the duct
EN-EL decided to postpone the cable tray installation over the ceiling, waiting for the new CV duct to be installed

8. Current status of the project
This week SMB should install the concrete slab for EN-CV (depending on the weather)
The works will stop from 22/12/2017 to 09/01/18
SMB Work Package is almost completed. Only exceptions are:
Concrete slab for EN-CV
Painting on the road (parking places, etc.)
Modification of emergency doors

15. Safety coordinator
John Robert Etheridge (164647) is the safety coordinator of P1. He will help TC to ensure that all the works will be done according to the CERN safety rules. For all WPs, a VIC shall be prepared after the design phase and presented by the responsible of each WP to the safety coordinator before starting the works. John is invited to this follow-up meeting so that he can be informed about on-going activities and can control that all foreseen/incoming activities are properly planned from the safety point of view.

16. Power consumption
The Users are planning to test in the SR1 cleanroom 1/8 of the entire ITk services
On 28/11/2017 TC had a meeting together with the Users (Dave, Susanne, Kendall) and EN-EL (Thierry) trying to better understand the situation. The results of the meeting are listed below:
For the moment it is not yet known the amount of power that will be required:
PP2s are not yet designed
An additional chiller will be required, but still not defined
In SR1 there are:
one (existing) switchboard (EBD5/1R) of 630 kVA (≈580 kW and 910 A) serving the racks area and the HVAC. The measures done show that between 12/2013 and 06/2017 the average served current was 180 A, with peak values around 360 A. This switchboard has several spare circuits that can be used. If the new HVAC system will have the same power consumption of the actual one (230 kW), there should be at least 350 kW available
one (new) switchboard of 250 A serving the cleanroom power outlets

17. Doors for emergency exits
In order to maximize the external view and natural lighting, TC requires the fully transparent doors for the emergency exits  SMB has to change doors
As specified during the design phase and again in the sent on 12/10/2017, the door of the emergency exit shall:
Have a panic bar (push bar) inside to easily open the door in case of emergency
NOT have the outside handle: the door must be used only in case of emergency  and shall not be opened from outside (the lock shall be removed)
Be airtight (at least class 3 according to EN-12207) and compliant with the Swiss law

19. Rear concrete slab for CV structure
An extension of the concrete slab behind SR1 (below the current smoke extractor) is needed by EN-CV for the installation of the pre-treatment device.
The new slab will continue (same height) the existing one and it will avoid the conflict with the separator access.
SMB is waiting for a price estimation from the contractor
The mechanical structure has to be modified (removal of the lowest horizontal beams) during the EN-CV devices installation. TBC if the modification need to be permanent

20. Cleanroom ceiling reinforcement
Actual test area
Radiation lab
Existing cleanroom
According to SMB calculations,
MAX 2 people can work on the ceiling in the same panel/point
Future extension
Scaffolding have been installed on 27/09/2017 as schematically shown in the picture above. They will be in place until the end of the works (or until the replacement of the existing ceiling (with a walkable one)

21. External windows requirement from HSE
The building extension is not compliant with the Swiss law, due to the absence of external views and natural lighting
HSE required to TC a formal approval process
On 11/10/2017 TC sent to HSE the Users’ motivation to justify the absence of external window and natural lighting. The motivation is the following:
While assembling the ITk, we will be working with glues and epoxies that will require very stable conditions with respect to temperature and humidity.  Windows allowing light to enter will make that more difficult to manage.  Also, we will want to test detector components multiple times during the assembly process, but their performance is temperature dependent.  Having a local change in temperature of one or two degrees will alter detector performances in an observable way, which complicates performance comparisons.  Our objective of building the best, most reliable detector possible demands a high level of stability and control of the environment in which we build it.
TC and HSE prepared the document for the approval process. The document was circulated on 30/10/2017. On 02/11/2017 TC received the green light to proceed from HSE. The approved derogation can be found here on EDMS.

22. Position of lights switches in SR1 cleanroom
ACCEPTED

23. Lights switches ACCEPTED
Each spot ( ) will contain one two-button switch Each switch should be embedded in the wall and as much as possible airtight. ECOFRED suggested that the switches shall have an International Protection Marking at least IP54. EN-EL proposes to install the following type:
ACCEPTED
The basic idea is:
One button turns on/off all the lights in the extension and the second button turns on/off all the lights in the existing portion

24. Position of power sockets in SR1 cleanroom
ACCEPTED

25. Power sockets ACCEPTED As already agreed, each spot ( ) will contain:
4x 220V - 16A (CH standard)
1x 400V - 32A
Local differential switch will be installed on the new switchboard
Each sockets should be embedded in the wall and as much as possible airtight. ECOFRED suggested that the power sockets shall have an International Protection Marking at least IP54.
EN-EL proposes to install the following type:
ACCEPTED

26. Position of Ethernet sockets in SR1 cleanroom
ACCEPTED
Single socket
Double socket

27. Ethernet sockets ACCEPTED
Each spot ( ) will contain one double socket and each spot ( ) one single socket Each Ethernet socket should be embedded in the wall and as much as possible airtight. ECOFRED suggested that the Ethernet sockets shall have an International Protection Marking at least IP54. IT-CS proposes to install the following type:
ACCEPTED

28. Lighting
The current lighting level in the actual cleanroom is 400 lx.
Due to the absence of external windows and natural lighting the Swiss law requires as compensatory measure to have at least 600 lx, with a C.R.I. ≥ 90 and a color temperature between 5300 K and 6500 K
Users (Danilo) requested a lighting level of at least 1000 lx (see on 20/10/2017).
ECOFRED will provide the following lighting system:
LED lighting units with a C.R.I. = 90 and a color temperature of 6500 K
Lighting level of at least 1000 lx at the working place with a Uniformity Ratio of 0,7
ACCEPTED

29. Taken decisions ACCEPTED
On 14/11/2017 HSE gave the green light for the layout of the parking places shown in the picture above

30. Small pillar that cannot be cut
the last small pillar of the cleanroom is connected to the main structure holding in place the material lobby’s walls
Even though it has been agreed that all small pillars will be removed, the last small pillar cannot be cut
The presence of this pillar is not affecting the new CV duct Also the horizontal beam has been checked and it is not an issue. However SMB agreed in removing/displacing the beam if necessary
TC propose to encapsulate in the same enclosure of the CV duct
ACCEPTED

31. Proposal 3 for CV inlet duct encapsulation
No encapsulation
Encapsulation V3
ACCEPTED
Only the duct, the small pillar and the central cross of the metallic structure are encapsulated
The opening for grounding proposed by EN-EL must be displaced by 150mm
Worse for cleanliness point of view (inclined surfaces can collect the dust)
Smaller surface lost in the cleanroom: 1.33 m2 on the floor and 2.77 m2 from 2.3m from the floor

32. Cable trays and enclosures
ACCEPTED

33. Antistatic floor of the extension
SMB proposed the following flooring solution:
A first layer (primer) made of: Sikafloor 161
A middle layer (with antistatic properties): Sikafloor 220 W Conductive (RG: 103 ≤ R ≤ 104 Ω)
An upper layer (protective and ESD): Sikafloor 262 AS N (RG≤ 106 Ω)
According to Sylvain, the proposed solution is more than enough for the purposes of the cleanroom.
Users agreed to this proposal (see from Kendall on 10/09/2017)
SMB can proceed with this solution
ACCEPTED

34. New proposal for CV inlet duct
ACCEPTED
The blue duct now is not crossing anymore the room over the ceiling, but below the floor
The big mobile sink has been temporarily disconnected and displaced
The position of the lighting units must be updated
Two proposals for the encapsulation of the ducts (see next slides)

35. Position of the permanent fan coils for R-C04-A
Left
Right
ACCEPTED
Dimensions of each unit:
Width: 1600mm
Height: 700mm
Depth: 300mm
This will be removed by EN-CV
To be displaced by the users
To be displaced by the users
EN-CV will dismount the current grills (when possible/useful). The two proposed locations for the fan coils of the permanent AHU in the test room are shown in the above pictures. They have been approved by Kendall on 16/08/2017 and by Didier on 21/08/2017.

36. Temporary AHU in R-C04-A
More details and information about the TSH060 unit can be found here
This temporary AHU will be placed outside SR1 (back side) to supply fresh air (hot and cold) in the test room (R-C04-A). The unit will be in use from November 2017 to June 2018.

37. Electrical matters
Current 160A switchboard will be replaced by a 250A switchboard (maximum possible considering actual electrical consumption, future general needs and current transformer capacity).
The order for the new switchboard has been sent on 07/07/2017. Total cost is ≈35kCHF
According to Thierry calculations (see of 30/06/0217) a maximum of six 380V-32A sockets can be used simultaneously in exceptional cases:
4 devices running on 380V-32A sockets can work at the same time with no constraints
It should be possible to add 2 more temporary
Grounding works are completed

38. Schedule for ITk Pixel tests in SR1
April-August 2017: test of prototype with one full cooling line ~375 W in SR1 (August 2017)
September 2017: commissioning of system setup in SR1 (power needed, few days of outage can be discussed, CO2 partially needed for commissioning)
October-November 2017: assembly of prototype in SR1 (power and CO2 needed, days of outage can be discussed)
November 2017-November 2018: systematic evaluation of demonstrator in SR1, dedicated test bench for comparison of DAQ, readouts, powering, cooling (power and CO2 needed). Short periods of outage can be discussed: a possible solution is to run power extension cables from the nearest building, if needed(tbc)

39. Schedule for ITk Strips tests in SR1
April-September 2017: Testing of pre and post irradiated modules in SR1 + Testing cold (-35°C) with chiller
September-December 2017: assembly of parts for system test setup for a Strip Stave in SR1
January-November 2018: Commissioning of system tests of a stave (CO2 cooling, interlock, DCS, DAQ, cabling)
As agreed with Susanne and Jens, short periods of outage can be discussed

40. Taken decisions
Services cannot arrive from below the fake floor into the pillars: pillars do not go through the fake floor, but they are loading the concrete floor. Openings are present in the concrete floor, but far away from the pillars.
The only possible solution is to run the cables over the ceiling and enter from there into the enclosures.
Cable trays and enclosures shall not cross the rails in order not to lower the ceiling in the assembly region.
The users required to have a minimum height of the ceiling of 3.7 m
The option of lowering the current ceiling (panels are 4.15m high) has been discarded

41. Taken decisions The clean room will be ISO 8 according to ISO 14644-1
All cable trays shall be covered
WP3 (EN/EL) will take care of all the cable trays related to main electrical services, while WP4 (TC) will take care of the cable trays for electrical controls. Users shall specify their needs ASAP
ESD precaution will be obtained with mats, people grounding and NO new antistatic floor is foreseen in the radiation lab
The SR1 radiation lab can be used by ITk tasks, but needs to be cleared with 1-2 months notice in case of TC/detector needs during EYETS

42. Taken decisions
13 power boxes will be installed by EN/EL. One power box at each of the 4 pillars between existing room and extension (the central pillar will be removed) and one power box every 3-4 m on the wall (evenly distributed). Each power box shall have at least:
4x 220V - 16A (CH standard)
1x 400V - 32A
Local differential switch for each sockets group (one for 4 sockets 230V-16A  and one for socket 400V-32A)
2 existing sockets boxes will be kept on UPS network (in the pillars area). No additional sockets on UPS network are required
Existing UPS network details: 100kVA lasting approx 10 minutes at 80kW (see from Thierry sent on 28/06/2017)
LED Lighting providing ≈1000 lux

43. Taken decisions
EN-CV will switch off the air conditioning and ventilation for at least 6 months (schedule should meet SMB’s one)
EN-EL will switch off the electricity for small periods of time (schedule should meet global schedule and users’ schedule)
Overpressure targets:
Overpressure of extended clean room (R-C04-B) is ≥15 Pa
Overpressure of radiation lab (R-C14) is ≥15 Pa
No overpressure in the test zone (R-C04-A), changing room (R-202), other areas
Overpressures of R-C04-B and R-C14 can be manually regulated in order to create slight overpressure of the clean room over the radiation lab if needed

44. Will be removed before starting
Taken decisions
The proposal of extending the changing room R-202 by ≈1m has been accepted. The drawings have been modified
To be removed
Will be removed before starting
≈1 m

45. Taken decisions Eric agreed on 16/05/2017
Two rails are required to drive the coaxial installation of the ITk.
These rails will be:
2 different rails, one flat and the other with a V shape (see drawings from Roberto)
Parallel to the extension long side (centered wrt the opening)
36.5m long and 2m apart ending 7.5m outside the building
Embedded into the floor
No particular tolerances have been added (default tolerances are considered)
There will be a 3m x 8m concrete slab that will host the outside rails and will create a flat area (currently there is a slope) at the same level of the inner floor
SMB shall update the design of the concrete slab
Eric agreed
on 16/05/2017

46. Taken decisions Eric agreed on 16/05/2017
An additional door has been required on the North-East-short-side wall of the extension, to ease the extraction of the ITk assembly.
SMB will design an opening (2.8m wide and 3.5m high) centered in the N-E short side of the extension .
This opening will be closed with a removable wall (not with an external door). This removable wall can be removed using a crane.
The cleanroom will have a correspondent opening of the same dimensions and will present either an internal double door or another system to guarantee the sealing.
Eric agreed
on 16/05/2017

47. Cooling and Ventilation stop
The stop of CV system for at least 6 month announced by EN-CV and due to the replacement of the AHU and upgrade of the CV system will cause major problems in the ID test area
Didier, Anatoli and Dave agree that during such a long stop of the air conditioning, the test cannot be performed
A solution has been discussed among Didier, Alex and myself. It has been presented to all involved people and it has been agreed (see next slide)

48. Temporary solution for R-C04-A during CV stop
The main points which have been agreed from both parties are listed below:
EN-CV will switch off at first only the portion of the system close to the demolished wall (where they have to work), keeping on the system on the other side of the cleanroom (test area and radiation lab). This will lower at the minimum the amount of time people working in SR1 are affected from the CV stop.
To grant fresh air (especially when the R-C04-A will be divided from R-C04-B), the upper door above the emergency door of R-C04-A can be kept open (see attached file).
Being an internal building (building into a building), the SR1 cleanroom should not have huge problems regarding the temperature. Especially in winter time and considering the power dissipated into the test area, the temperature should not drop drastically. Anyway, just to be sure to have always acceptable working conditions, one or two mobile inverter air conditioner can be provided (the cost estimate is roughly around 3-4 kCHF each) so that also people in the radiation lab can adjust the temperature in their working area.
Alexandre will add these points (even if they are related to a temporary solution) into the “Upgrade of SR1 clean room” document prepared by him and circulated for approval.
