DHCAL Overview José Repond Argonne National Laboratory CALICE Collaboration Meeting DESY, Hamburg, Germany March 20 – 22, 2013

2 Activities of the Next Year Emphasis on data analysis R&D with resistive plates (decrease resistivity and increase rate capability) Build and test RPCs with new Bakelite plates (new, lower resistivity Bakelite, Bakelite with resistive paint layer inside the plate) Build and test RPCs with new, semi-conductive glass plates 1-glass RPCs (pad multiplicity ~1, resistive layer not critical, thinner, higher rate capability) Build more large chambers and continue to test Set-up of large cosmic ray test stand with DHCAL layers Development of next generation readout (token ring passing, lower power consumption…) Currently on hold (no funds)

3 Plans for Publishing Test Beam Results Instrumentation paper On hold due to missing electronics measurements (sensitivity) Draft exists Electronics paper On hold due to missing electronics measurements (sensitivity) Draft exists Noise paper Analysis started Student left Studies need to be completed At the moment no manpower Muon response paper CALICE_Note exists Analysis virtually completed Fe-DHCAL

4 Plans for Publishing Test Beam Results Pion/positron/calibration paper Analysis well advanced CALICE_Note being drafted Pion shower shapes Analysis ongoing Still ways to go Longitudinal calibration paper Analysis virtually completed Thesis exists CALICE_Note to be drafted Fe-DHCAL

5 Plans for Publishing Test Beam Results Combined Si-W ECAL + DHCAL data No concrete plans to analyze (yet) Minimal absorber data No concrete plans to analyze (yet) W-DHCAL data CALICE_Note exists with response/resolution Analysis being taken over by CERN group Software Compensation with W-DHCAL data W-DHCAL better suited than Fe-DHCAL No concrete plans (yet) W-DHCAL DHCAL Fe-DHCAL

6 Plans for Test Beams after Shutdowns Fe-DHCAL data Completed W-DHCAL Completed Tests of individual RPCs/GEMs High rate RPCs (GIF, FNAL) 1-glass RPCs (FNAL) GEM prototypes w/ or w/out DHCAL (FNAL)

7 Overall Goals for the DHCAL No matter what Complete test beam analysis and publish Develop and test high-rate RPCs Built and test more 1-glass RPCs Seek involvement in other experiments where RPCs might be needed Assuming no ILC project in near future Increase involvement in ATLAS upgrade Look for other possibilities to utilize RPC technology Assuming ILC project materializes Activities need to be coordinated with new reality: detector collaborations? Design and prototype next generation readout (low power, better time-stamping resolution, higher channel count...) Build and test gas recycling system (Iowa) Continue work on HV distribution system (Iowa) Start work on LV distribution system (DC-DC converters?) Re-start work on HCAL engineering design
