Systematic Study of Saturation Correction for ScECAL Beam Test Analysis

This study conducted at Kyungpook National University in Korea evaluates the saturation correction in ScECAL data analysis, exploring the effective number of pixels (Npix) using pseudorandom experiments. Analysis of channel-by-channel data changes reveals deviations in resolution and linearity. With 20 trials across stochastic and constant terms, results show variations of approximately 0.3% and 0.24% respectively. Systematic evaluations on Npix demonstrate effects comparable to statistical uncertainties. The study aims to enhance energy resolution and linearity through MIP calibration, temperature correction, gain calibration, and inter-calibration correction. Utilizing ScECALDigitizer for MC event analysis, gain runs are proposed for systematics on gain constant and saturation correction.

  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
