1 SDD LVPS progress Vasily Kushpil Vojtech Petracek Libor Skoda CTU Prague ALICE week Utrecht

2 Outline  LVPS2 module – certification  LVPS2 module test in magnetic field  LVPS crate controller  Module production time schedule  News on HV control

3 Certification of the LVPS2 module  Design tuned to accommodate suggestions from EZU  Halogen-free PCB  Prototype module in production (ready end of June)  Certification during July/August

4 LVPS2 module test in magnetic field  Module tested up to B=450G  Different B orientation  Test performed at max. output power 70W – this exceeds max. power guaranteed by AREMpro (55W).  Dependence of efficiency on B measured B [G] P in [W] 

5 LVPS crate controller  Power management for LVPS crate  Rempte power ON/OFF (over Ethernet)  Measurement of power consumption  Master for all 7 modules in crate  TCP/IP interface  Ethernet HW designed for operation in magnetic field (like DCS board)  Prototype will be ready end of June

6 LVPS production  Full basic system (42 modules + crates + crate controllers) will be ready by Jan06  Modules will arrive in several batches which will be burned-in and tested at CTU and NPI Rez.  Q1/06 production of spare pieces

7 HV control & summary  HV modules will be available in July at INFN Torino  There we’ll start excercises with module programming and control during the summer  As soon as the HV modules arrive we’ll have all DCS HW and we’ll be able to finish the vertical slice of the SDD DCS  Implementation in PVSS will start in August
