  1. SDD Systematic Study @ Test Bench Energy and Time resolution • Optimal temperature • Energy resolution • Time resolution • Pileup rejection • Online: optimization of VETO time after “Reset” & large signals. • Offline: Flash ADC (in preparation), pre-gate, tail charge Optimal • Incident-angle • Some part of response function depend on incident-angle • But, peak position changes at most 0.5 eV Different Incident-angle Fe55 X-rays Fe55 Spectrum w/ Sr90 electron TestBench MnKa peak difference <0.5 eV MnKa TiKa MnKa MnKb electron ~1300 hits/sec NiKa For Calib.
