Market survey & Market survey & TenderTender Market survey
sent July – answer deadline end August 21 answers 5 companies qualified
Tender planning Out by end September 04 Answers end November 04 Contract end January 05
Technical Specification Draft exist Environmental considerations; limits to be fixed;
Normal environment Low-level B-fields only Radiation effects only High-level B-field and radiation effects
Modularity: size of modules/channels to be specified ALICE needs spans from 3.6A (SSD) to 250A (TPC)
Controls requirements to be fixed Remote control of voltages? Remote power on/off? Performance

ActionsActions
Finalize technical specification & launch tender – feedback from detectors needed
Tests of LVPS Wiener compact version for low level radiation - ESS Caen SY1527 for low level radiation and B-field – SSD Caen Sasy mainframe + 48V PS for low level
radiation and B-field - TOF Caen Easy crate for radiation and B-field - ESS Arem Pro for radiation and B-field - SDD
