FEE Installation & Commissioning TPC Meeting, 21 April 2006

L. Musa

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 RCUs May – 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 RCUs Mar – 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

FE Cards Installation 1/2

Organization and schedule

• 2 installation crews (3 people / crew)

• Installation started on the 30th 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

Measurement of VCCA, VCCD, IA, ID 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)

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

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
