Calice SiW Future plans
• Prototype tests completed successfully in June
• Minor modifications for VFE-PCB and
CaliceEcalReadoutCards identified
• VFE-PCB released for production in July
•
•
•
•
See talk by B. Bouquet
CERC redesign was finalised in August
Production boards being sent out for fabrication next week
Three week turnaround; start testing by end of September
• ECAL system tests from October onwards
• Initially at least 10 layers in cosmic teststand at Ecole Polytechnique
• DESY ECAL electron beam test from November onwards
• Initially using first 10 layers
• Build up over several months to full 30 layer ECAL
• Beam
tests with HCAL(s) in hadron
beams from 2005 onwards

Silicon/W, SLAC-Oregon-BNL
• Dynamically switched Cf
– Much reduced power
– Much better S/N
– Allows for good timing measurement

• 38 layers Calice Tile HCAL (new prototype)
• 30 * 220 tiles
• SiPMs with
coax cables
8 * 145 tiles
• ~ 8000

SiPM
1 m2 with 220 tiles
• Aim at common design for HCAL
and tail catcher (~350 channels)

Design for DHCAL* using Triple GEM
Embeded
onboard
readout
Ground to
avoid
cross-talk
Progress on understanding prototype signals and associated crosstalk.
Progress on large-scale GEM active layers.
Working with ANL/Fermilab on readout electronics (GEM mods to RPC design).
Working with 3M Corp. on GEM foil production.
Issue now is the funding/timescale for test beam stack.
*J. Yu On behalf of the HEP group at UTA.
Conclusions
A lot of activityies all over the world
QUESTION:
Is it possible to imagine a
global combined beam test
for all ( many of) the
proposed techniques?
