SC test stands
SC tests and umbilical trigger mapping
Have successfully run the UVa pulser system and ECAL DAQ with a preshower CREPE board
Complete system controlled from a single PC
Would like 1-2 further CREPE boards for additional test stands

Dee4 to H4 in MayDetailed design of mount on H4 turntable nearly complete
20 SCs = 500 crystals UVa offer for testbeam coordinator: Alexander Ledovskoy DAQ/DQM Matt Ryan, Alexander Ledovskoy, Yvgeni Vlassov CCS code and control room monitoring need to cope with - EE trigger mapping into the motherboards
- Readout 5 EE Trigger GOH/FE later in the year - Token ring layout specific to Dee4
H2 permanent facility
4 SCs in front of HE
Use old E0prime mechanics2 existing SCs at RAL and UVaAssemble 2 further SCs
Project led by HCAL communityThey will design/make all infrastructure interfaces at H2
