3. 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

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

7. LCcal Test beam results: Si Pad two particle separationPH
@ 2X0
In the next few slides I would like to show you the capability of our setup to record 3D images of the shower development within the calorimeter. In this first example the forward strips tracker triggered two particles impinging on the detectors and the two showers produced can be easily separated. Both in the lego as well in the box plot the 3d image on the 1st and on the 2nd layer is presented. The distance between the two hits is roughly a couple of centimetres.

11. 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.

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?
