  1. PIXEL CAEN Installation Status Presented by C. Newsom U. of Iowa March 31, 2008

  2. CAEN Status (1) • Cabling • Installation is complete. • Load testing and certification is complete (0% failures). • A1676a controllers at S4F01 (4 ordered, 1 borrowed) • 3 have been delivered • 1 is installed at P5 and is in use (2 needed) • 1 is at PSI • 1 is at TIF. One of these will be installed at P5 when the detectors move to P5. • 1 borrowed from CAEN is being used for A4603 burn-in at TIF. • 1 spare has been ordered and should arrive in June/July.

  3. CAEN Status (2) • MAO (48V crate power supplies) at X2F36 and X2F37 (8 ordered) • 2 borrowed supplies are installed, one on each rack. • 6 are on order with delivery expected in April. They will be needed in early May. • Burn in: Guido has promised to take care of this. • 2 spares should be delivered in July. • Crates (15 ordered) • 11 have been delivered (10 needed) • 10 are installed. • 1 is bad and is being replaced. • 4 are scheduled for delivery in July. • We will have 5 spares.

  4. CAEN Status (3) • Interlock cards (12 ordered) • 10 are installed at P5 (10 needed) • 2 are spares • The Patch panel wiring is underway and should be complete this week. • A4602 LV power supplies (18 ordered) • 17 have been received. • 12 are installed at P5 (14 needed) • 1 is in use at TIF • 2 are in use at PSI • All but the 2 PSI modules have been tested and burned in. • 2 failed and are at CAEN awaiting repair. • 1 is scheduled for delivery in July. • Eventually we will have 4 spares.

  5. CAEN Status (4) • A4603 LV/HV power supplies (56 ordered) • 22 have been received. • 13 are installed at P5 (48 needed) * • 4 are in use at TIF* • 2 are in use at PSI • 1 failed and is at CAEN awaiting repair. • 2 are awaiting certification and burn-in. • 8 are scheduled for delivery tomorrow. • 24 more will be delivered in ~1 month • 2 will be delivered in July. • Eventually we will have 6 spares.

  6. Certification and Burn-in Needs • TIF • We have 4 load boxes and can certify and burn-in 8 modules per week at TIF. The tests are not quite as thorough as what is done at Prevessin. • Certification of RMS noise OV, UV, OC trips etc is done but other tests are not performed. • CAEN has indicated that we will have 10 more modules to “certify” and “burn-in” this week. • We should recertify and burn-in all A4603 modules at Prevessin if this is possible.

  7. Overall CAEN Status • We have sufficient power supplies ready to commission ½ of either the Barrel or Forward Pixel detectors right now if we use both racks. • In ~2 weeks that fraction will double but we will need additional MAOs to take full advantage of this. Ideally, we would want all 6 MAOs in place 2 weeks before the barrel insertion on May 26. • That is sufficient to commission our detectors during installation although it is not optimal as it requires moving the A4603 cables. Simultaneous running of both detectors relies entirely on the CAEN 4603 and MAO delivery schedule.
