Migration PNPI HV-system to USB interface
SW status:
1. HVServer is in progress:
New features:
- soft trip
- automatic recovering in simple cases
- log file with alarms, trips, etc. will be created by server
2. Test and Calibration SW (LAB) is under developing:
- accuracy of current calibration will be improved
- some bugs in voltage sensors calibration are fixed
- test SW will be unified in according of our present conditions
3. Calibration in situ --- in the list of jobs to be done.
4. PVSS part – still under discussion.
- the primary power supplies control has to be implemented in PVSS.

UF-PNPI HV system. Stage 2 proposal
Current status of the HV system connection and needs
56 RDB installed on the detector.
Total outputs (1 output = 4 HV channels)– 504
Used – 480 outputs
Spare – 24 outputs
Directly connected to chambers – 320 outputs
Connected via splitter x4 – 160 = 640 outputs
Total chambers connected – 960
Need to replace – 640-160-24=480 outputs 1 51 RDB
Unfortunately we need to spread all RDB for 8 places
So minimum number per position 7 RDB
Total we need to install – 56 RDB

UF-PNPI HV system. Stage 2 proposal

To complete HV system we need install more:
- 56 RDB
- 8 Master Boards (MB)
 We have spare:
- 10 RDB + 1RDB without regulators.
- 2 Master Boards
(Assume that it is enough as a 10% of 110 RDB and 16 MB)

To have ~10% of spare RDB and MB plus 10% of spare regulators
we need to produce in total:
- 56 RDB + 400 spare regulators
- 8 MB + 16 spare regulators

We need replace LV power supply to feed more RDB

Comments for price estimation
•
•
•
•
Assume that production of the modules will be at PNP
System assembly and initial test will be in PNPI
Final test and installation – in CERN
All prices for components are based on the previous experience, so
it is not final and used for estimation.
• The total number of components is about the same as in the first
stage, so the price should be almost the same
• Some money needs for shipping/receiving it is not included
