  1. LV Power SuppliesTB 10.5.05/L.Jirden • Open issues on the LVPS offers • Assumed solutions for ALICE • Input from Detectors • Next steps

  3. Output protection for Wiener PL500/F12 • Existing protections are CPU dependent • Over Voltage protection • Over Current trip • Constant Current limitation • CPU watchdog • CPU Stop protection – independent of CPU • Proposed improvement • Voltage limitation • Pure hardware limitation independent of CPU • Limits output voltage to a user defined value fixed at factory • CPU watchdog • SEU strategy implemented • Development cost: 10kCHF • Acceptable scheme? TPC, HMPID to give opinion • Meanwhile we have assumed that an acceptable solution can be found

  6. Request to detectors • Prices and examples sent to all detectors • Detectors asked to define • Their solution • Needs for test samples • Final needs including spares • Required delivery date

  7. Detector answers • Answer from 8 detectors so far • MTG, FMD, SPD, TPC, HMPID, MTK, PHOS, CPV • Special cases • TOF: separate CAEN solution and contract • SDD: separate AREM PRO solution and contract • ZDC: no LVPS • ACORDE: no LVPS

  13. Next steps • Conclude on Wiener F12 output protection: end May • Acceptance test of Caen + Wiener solutions: piecewise until October 05 • Detectors to select solution and define: final quantities, delivery dates and the need of test samples in consultation with Fabio + Lennart: end May • Detectors to define: cables, connectors, interlocks, and rack layouts including cooling: end June • Detectors to issue firm order: ~6 months before required delivery
