1.Introduction
Calorimeter under study
: Lead/plastic-scintillator Sandwich with Hardware Compensation
Baseline Study
Option under Study
Tile/Fiber Structure (CDF/CMS-style)
Scintillator-Strip Array
Multi-channel HPD readout
EBCCD (or SiPM)
WLS-readout Scintillator-Strip SHmax
Direct-attached APD-readout SHmax
Previous Studies on Energy Resolutions:
testbeam measurement at
KEK
and FNAL
EMcal with 4mmPb+1mmSci :
σ
E
/E = 15.4%/√E + 0.2% for
electrons
HCAL with 8mmPb+2mmSci :
σ
E
/E = 46.7%/√E + 0.9% for
pions
Previous Studies on Granularity Optimization:
Hadron-shower fluct.
eigen-vector
analysis:
7~8
longitudinal segmentation sufficient for e/p ID
No testbeam studies on transverse segmentation (except for the present one).
Simulation studies quite unsatisfactory yet.
