1. Future Beam Test Plans of the Calorimeter Group Aug-6 2007 学術創成会議 Satoru Uozumi (Shinshu) for the GLD calorimeter group We are planning to have two beam tests : 1.at KEK new beamline at Nov 2007 2.at Fermilab in 2008 summer

2. 3 Types of Modules ① WLSF readout 13 layers ② Direct readout 13 layers ③ WLSF readout by extrusion technique 13 layers Beam FR ②①③①①② 13 + 13 layers

3. Beam position (mm) Signal (ADC counts) Fiber readoutDirect readout Extruded scint. Response uniformity of 3 different types of scintillators MPPC Beam Layer # Strip # Response for MIP (DESY beam test data) Fiber readout extruded

4. Hole size Why the extruded scintillator shows such low light yield and non-uniformity?

5. Objectives of the KEK beam test Check performance of various scintillator strips using the high energy beam –Evaluate light yield, response uniformity, variation –Compare characteristics of 3~4 different scintillators –Need to establish extruded scintillator strips for next ECAL prototype beam test in 2008 at FNAL

7. Beam Test Plan (tentative) MIP scan of the scintillator strips MPPC signal are read by CAMAC ADC Tracking with Sci-Fi tracker (position resolution ~ 1mm) 2-3 people from KNU (Korea), 2-3 from Japan Very tentative schedule : –~ 3 days for setup (need 1-2 days access to beamline) –~ 3 days for beam run (including 1 day commissioning) –~ 1 day for withdrawal Strip scintillators Beam Sci-Fi trackers Trigger counters

8. 2008 summer : The FNAL beam test Establish the Scintillator-ECAL –Evaluate all the necessary performances using various beams ( ,K,e,  ….) with wider energy range –Make the SCECAL ready for the engineering design Combined test with the Analog HCAL Test  0 -> 2  reconstruction Measure hadron shower to test simulation model –Compare the result with various models –Precise hadron simulation will help study of PFA

9. The 2 nd SCECAL module (At least) 4 times larger than the DESY BT module. (Still need simulation study to determine the module size, depth, strip size) Fully adopt extruded scintillators Expect several thousand channels

10. Beam test related Jobs for mid-term Collect information about FNAL beam test facility (always) Detector optimization using Jupiter simulation (always) Beam test simulation based on Mokka framework (~fall) –Simulate SCECAL performance –  0 reconstruction test Establish extruded scintillator (within this year) –Perform a beam test in November at KEK? R&D of MPPC readout cable (~fall) Mechanical design and test of the entire module construction (within this year) Establish gain and temperature monitoring system (this year) –Test LED light distribution system with acryl bar and fibres –Mechanical assembly of the system –Learn CANbus operation MPPC mass measurement (system construction in this year) Feedbacks from the DESY beam test analysis (ASAP)
