  1. SDD LVPSprogress Vasily Kushpil Vojtech Petracek Libor Skoda CTU Prague 14.6.2005 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

  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
