1. 1st Discussion for RICH Cabling: ‘long distance’ cables and electronics install
General aspects:
Optical links :
last discussion with Steve in Oct
March 2016 (TB): option approved to split 144 fo cable to single fibre in TELL40 side (load balancing, Data & ECS+TFC mixing possible, ECS bidirectional links) for all Sub-detectors  could simplify the cabling inside RICH detectors
General schema to reconsider ? Steve
Documentation to prepare: §2 about VTTx, VTRx quantities… to complete by Steve
- Copper cables
Doc and cable/dataBase software:
“1-Can you please give us a contact person for fibre-optics and a contact person for copper-cables.
(it can be the same person!). He or she can then be the point of contact to finalise the documents with Laurent
and also provide information on re-using old cables, ordering & installing new cables, rack infrastructure etc.”
Fibre-optics: Steve
Copper-cables & racks: ?
“2-Gloria and colleagues have developed a new interface to the cabling database ( )
It could also be used for your ‘internal’ cabling.
An e-group will be created for each sub-detector, and the members will have the rights to modify the cabling details of RICH.
Can you please let us know who should be in the e-group.”
In demo for the moment: few names to test it and for the future ??

2. RICH Copper cables and Power supplies
Info below extracted from “Infrastructure requirement doc” (Heinrich)
Many information already there: Thanks!
LOW VOLTAGE
no need more additional Maraton
One Maraton take from RICH2 to install for RICH1  2 controls+1 Power cables to install (D3-Balcony)
HIGH VOLTAGE
“The existing cables are not sufficient and not appropriate for the new voltage partition”
4 x 56 wires cables for each RICH detector to install ? (36 wires cables not reused)
Time and Exposure Calibration
2 new systems in D3 (CW Laser, Hamamatsu Driver)? New cables, optical fibres ?
DCS (ELMB for diff Temp, Pressure,…monitoring)
ELMBs detector side. Reuse the CAN bus cables in place, no need new cables.
Remote power switch available for 2 D3 racks
Does ‘intelligent’ PDU (Power Distribution Unit) with Ethernet connection could be a solution?
DSS
Rich is interested to have additional ‘safety parameters’ monitored by DSS
Could be detailed in a dedicated meeting  a contact person ?

3. LAMS and MDMS systems for RICH1
MDMS  to remove
LAMS ?
New systems will be installed ?
Power cables + breakers

4. Laser system in D2 for Rich2
Keep it ? New system?
Space in D2 rack, cables (power, can, optical link)

5. D3C01 (Level1 Board-Rich1) 2 Wiener crates to remove UKL1 Boards
Optical fibres
Optical PP to remove

6. D3C02 (Maraton + HV – Rich1) 3 Wiener Maraton: kept
HV system Caen Crate: kept ?
HV cables
Light detection system: change ?

7. D3C03 (HV-Rich1) HV system: change ?
New customized HV supply, correct ?
Removed old cables, install new ?

8. D3C04 (Level1 Board-Rich2) 2 Wiener crates to remove UKL1 Boards
Optical fibres
Optical PP to remove

9. D3C05 (Maraton + HV – Rich2) 4 Wiener Maraton kept
HV system Caen Crate: kept ?
HV cables
Light detection system: change ?

10. D3C06 (HV-Rich2)
HV system: change ?
crate
cables

11. D3C07 (Laser)
2 LASER systems kept ?

12. D3C08 (Tests? Rich2)
Kept ?

13. D3 Barrack to view
8 x D3 racks are need for RICH1 + RICH2 ?
or considering that Level1 racks will be emptied
D3C07, D3C08 could be ‘given’ to someone if need ?
2 racks in the Bunker for RICH2 are enough ?
2 racks on the Balcony for RICH1 are enough ?

14. Old cables table (before installation): additional cables probably installed since
RICH1 (table1) * *
* to remove

15. RICH1 (table2) * * * * *
