1. 1 FEE Installation & Commissioning TPC Meeting, 21 April 2006 L. Musa

2. 2  Installation of FECs and Backplanes Jan ’05 - Mar ’06  electrical and functional test of each FEC  test of the connection between FECs and pad plane  test of the connection between FECs and readout backplane PHASE I  Installation of RCUsMay – Aug ’06  Comprehensive test of all (216) readout partitions: FEE, DAQ, DCS, TRIGGER, HLT, ECS (power bars and cooling required) PHASE III  Characterization of the whole system with RCUsMar – May ’06  Characterization of 1 readout partition at a time: noise, gain, width, baseline, time offset, temperature, voltages and currents PHASE II Electronics Installation and Commissioning Schedule

3. 3 FE Cards Installation 1/2  Organization and schedule 2 installation crews (3 people / crew) Installation started on the 30 th January Installation rate: ~ 1 sector / day  Status Installation of FECs completed (on March 15), with exception of 1 sector on C side Installation of Readout &Control backplanes completed by end of March, with exception of 1 sector on C side The electronics of 1 sector (A09), equipped with the LV bus rods and cooling, was characterized (pedestals, noise, gain) The electronics of sector A08 is under test

4. 4  Measurement of VCC A, VCC D, I A, I D and T  Measurement of the FEC Identifier FE Cards Installation 2/2 During the installation, the FECs are tested individually (stand-alone) by means of a dedicated “mounting test tool”, U2F (USB to FEC interface) U2F Card  Readout of trigger related data (pulser) Connection to the pad plane

12. 12 Power Regulators RCU status and plans … Readout Control Unit 1/2 DCS CARD SIU CARD

13. 13 Readout Control Unit 2/2  Mass Production (240 units including 10% spares)  completed November ‘05  Mass Test  completed December ’05  Delivery of tested DCS cards Mar ‘06  Delivery of tested SIU cards (DAQ project):  1 st lot (108 units)Mar ’06  2 nd lot (108 units)May ‘06  Assembly and final test of RCU + SIU + DCS: Apr – Jun ‘06  Installation and commissioning of RCUs: May – Aug ‘06 Production, test, installation and commissioning

14. 14 Preparing for Commissioning Phase III  RCU Lab - setup I  Final assembly and test of RCU + SIU + DCS  25 FECs (readout partition) + Backplane + RCU  1 DAQ PC (PCALD23) + single-channel RORC  1 DCS PC (local network DHCP server, DIM Server) + Ethernet Switch  Local Trigger Crate (SBC, LTU, TTvi, TTCex) + TTCoc  RCU Lab - setup II  TPC FEE + DAQ + HLT Integration  2 x Readout Partitions  1 DAQ PC (EPAITBEAM02) + dual-channel RORC  1 HLT PC + 1 HRORC  P2 SXL2 – Test of the electronics, 1 Sector at a time  1 x Readout Partition  1 DAQ PC (ALDAQPC021) + dual-channel RORC

15. 15 Conclusions  Installation of FECs almost complete (97% done)  The complete electronic chain of one TPC sector has been characterized  gain, baseline and noise distributions well within specifications  Installation of backplanes was completed by Mar ’06  Installation and commissioning of RCUs in May - Aug ‘06
