SR1 extension follow up 03-Jul-17 Marco Ciapetti

Introduction SMB matters Electrical matters Updated PBS Safety Coordinator Updated schedule Taken decision Things to be decided

SMB matters SMB started the earthworks and networks deviation. This task will continue until the end of July. The problem of the discovered unknown network is solved: It was an old HV network, not any more under power. It has been removed This cause 3 days of delay, but not on the critical path The additional costs have been covered by the contingency Drawing regarding the concrete are complete and the approval process has been started. You can find them on EDMS here ECR have been approved on EDMS for the new external concrete slab (here) and for the new lateral opening (here)

SMB matters Due to some networks works in the area close to the SR1 main door, SMB needs to temporarily close the access through that door. Period of intervention has changed: The door will be inaccessible until the end of July 2018 If some temporary access is needed, Please contact Pierre Cardon (167840) Please, spread this information to whoever can be affected. Sorry for the inconvenience that this might cause.

Electrical matters Current 160A switchboard should be replaced by a 250A switchboard (maximum possible considering actual electrical consumption, future general needs and current transformer capacity). The extra cost will be around 6kCHF (agreed by TC). According to Thierry (see email 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 will be done on week 28 and 29 (in agreement with SMB)

Electrical matters 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 email from Thierry sent on 28/06/2017) Lighting will provide the same illumination of the actual clean room (≈400 lux) Type of lights: LED (to minimize the maintenance)

Safety coordinator John Robert Etheridge John.Etheridge@cern.ch (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.

EN-EL, IT-CS should also start working Apr 2018: target for ending clean room extension installation and commissioning May 2018: target for ending ducts and HVAC system. IT-CS and BE-ICS should complete their commissioning Jun 2018: EN-CV should complete the commissioning Jul 2018: target for commissioning the SR1 clean room extension

Taken decisions A power outage of 1 or 2 days will take place during TS2 (currently scheduled for mid September 2017) in order to replace the electrical switchboard 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 ESD precaution will be obtained with mats, people grounding and NO new antistatic floor is foreseen in the radiation lab 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

Things to be decided Number and position of Ethernet inputs: 25? (tbc) Total expected power consumption (Pixel/Strip integration, testing, standard activities): (tbc) Amount of cables and services needed by the user (total cross section, distribution, feasibility of reusing part of the existing cables, etc.)  tbc Path for cables and services (below fake floor and along pillars or cable trays etc.)  tbc

Things to be decided 4 openings (one at each corner) have been requested (by Thierry on 30/05/2017) on the sandwich panels of the walls in order to install and access the grounding loop. This will be added in the technical specification, but a drawing with the exact dimensions and locations is needed  Thierry

New requirements DRAFT cost estimation SMB subject Technical impact Extra cost estimates New opening (WIDTH = 2.8m, HEIGHT = 3.5m) Update of the steel structure design (drawing + calculation note) Supply and installation of the “door” 2000CHF   15000CHF 2 new rails in the concrete slab Update of the concrete structure design (drawing + calculation note) Supply and installation of the rails 1500CHF 30000CHF 18 945.00€ (≈20000CHF) New exterior concrete slab (8m*3m) concrete structure design (drawing + calculation note) Civil engineering works 1000CHF 9600CHF ≈50 kCHF NOTE: A new work package have been created (WP7: “rails”). It is managed by Roberto Rinaldesi (EN-HE) and it will take in account the supply and installation of the rails. WP1 “civil engineering” (SMB) will managed the 2 necessary trenches 400mm x 70mm and pouring of non-shrink grout

Ceiling Lowering A rough cost estimate has been asked to ER2i and STIC (ER2i did not do a survey, while STIC came and studied the situation): ER2i STIC Assumptions: no intervention is foreseen on electricity (drillings and cuttings are included, but not the equipment, lightings…) No dismantling of the existing ceiling CERN shall remove first cable trays Rough cost estimation: Handling structure: 32 K€ PU ceiling, 80 mm thickness: 48 k€ Cuttings / drillings: 6 k€ Survey, lifting, project management: 10 k€ Assumptions: Lighting is quoted separately Ceiling will have a rigid structure that allows one person to work on it No dismantling of the existing ceiling CERN shall remove first cable trays Rough cost estimation: Handling + structure + sandwich panels + scaffolding: 63 K€ Lighting embedded in the ceiling (60 units LED): 25 k€ 96 k€ 88 k€ TC will add the ceiling lowering of the existing part (not the radiation lab) as an option in the TS for the internal envelope

Electrical study Thierry completed the preliminary study for WP3: Regarding lighting, he propose to add 36 of this LED lights: The lights will be installed below the ceiling (as they are now) and not embedded into the ceiling. The cost estimation is: ≈10 kCHF (cabling excluded) In case the ceiling is lowered, new lights will be needed. The additional estimation is done for: Disconnection and removing existing lights Buying new lights (33 units) Connexion and fixing new lights (using existing cables) ≈10 kCHF Regarding sockets boxes, the job will be done in two steps: 1) disconnecting cables and removing existing boxes; 2) installation of boxes on metal pillars and connection of cables (after the external wall will be dismounted)  1 or 2 hours of power cuts will occur

Position of power boxes in SR1 cleanroom

Existing socket boxes Currently, there are several sockets boxes on the external wall in existing room.   Position 1 : 3 boxes with 400V - 4x16A socket (x2). 2 boxes with 230V – 2x10A (CH) socket (x4). One on UPS network. 1 box with 230V – 2x16A (CE) socket (x2). Position 2 : No need to reuse these, but in case they can be added on the pillars (opposite to the requested boxes)

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)

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

Taken decisions The clean room will be ISO 8 according to ISO 14644-1 All cable trays shall be covered

Rails 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) 36m 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

Opening on the short side 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

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

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

Bldg. 6115 re-connection Lukasz, Damien and Piotr are working on the re-connection of the CO2 barrack Piotr installed the protection wall for the PP2 Pixel rack asked by Didier Damien opened the hole in the radiation lab. This was done in two steps because some cables where passing behind the first hole location.

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)

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.

Anti-static floor The current cleanroom (R-C04-A and R-C04-B) has an antistatic (ESD) fake floor, while the radiation lab (R-C14) has not. Tests have been performed by Sylvain Kaufmann (TE-MPE-EM - 162670) on 24/05/2017 in the presence of Marco Ciapetti and Susanne Kuehn. The results are positive: Even though the resistance to ground vary from tile to tile, it was always 108 ≤ R ≤ 109 Ω Variation is caused by the cleanliness/dirtiness of the floor: in the same spot, it has been measured before cleaning 3.5 107 ≤ R ≤ 108 Ω, while after cleaning (with a humid tissue) 107 ≤ R ≤ 2.5 107 Ω. Measures were in some cleaner spots even R ≤ 107 Ω (best result that the used instrument can measure). On top of the ESD pads, we found similar results (even worse than the floor itself, when the pad was not clean). BEFORE CLEANING AFTER CLEANING SAME SPOT DIRTY SPOT ON THE PAD DIRTY SPOT CLEAN SPOT
