  1. ScECAL Fermilab Beam Test analysisScECAL Group MeetingKyungpook National University, Daegu, Republic of Korea,March 19th, 2012Adil Khan, Satoru Uozumi, DongHee Kim

  2. Saturation correction (effective num. of pixels (Npix)) Systematic Studybased on data randomly change parameter channel-by-channel, and perform pseudo-experiments. Observe the variation (RMS) in terms of resolution and linearity. Total 20 trials

  3. Stochastic term for 20 trials Effect is order of ~0.3% . Nominal value

  4. constant term for 20 trials Effect is order of ~0.24%. Nominal value

  5. Deviation from linearity (%) Effect is order of ~1.0%

  6. Deviation from Linearity (%) Effect is order of ~1.0%

  7. Systematics on Npixsummary • Effect is larger comparable to the stat. uncertainties.

  8. Systematics study summary in terms of Energy Resolution and Linearity

  9. Summary & Plan • Systematics (based on data) are evaluated • For MIP calibration • For Temperature correction • For gain calibration • Inter-Calibration correction • Try to use gain runs for systematics on gain constant • ScECALDigitizer to analyze MC events • For saturation correction
