Experimental Setup Analysis in JLab Hall C: EDC and Tracking Challenges

This document presents the findings from the JLab Hall C experimental setup, focusing on issues related to EDC residuals, tracking accuracy, and EHODO performance. The analysis highlights significant discrepancies in track alignment, particularly at EHODO1, and examines the implications of large residuals and chi-square values in tracking data. Several mysteries related to tracking inconsistencies and multi-hit occurrences within segments are discussed. The report concludes with a summary of findings and future action items, including positional analysis and further investigations into residual measurements.

  1. E05-115 experimental setup in JLab Hall C (2009) HES HKS meeting 22Nov 2010 T.Gogami

  2. Contents • EDC Residual • Tracking • EHODO • parameter

  3. EDC residual • Tracking code • Drift time , distance • EHODO Run : 76321 (CH2 target) σ ≈ 250 [μm] σ ≈ 300 [μm]

  4. EHODO timing Not so bad TDC of EHODO2 cannot be seen with current rev. Need to be checked

  5. xFP vs. Residual The center doesn’t match !

  6. Pos. at EHODO1 BLUE→ Hit only EHODO15 BLUE→ Hit EHODO15 These stripe structure caused by multi-hit (between segments) ちなみにthe center doesn’t match.

  7. Mystery 1 Large residual [cm] [cm]

  8. Mystery 2 [cm] HES track chi-square Large chi-square

  9. Summary and to do • Summary • EDC tracking • Large chi-square • Large residual • EHODO multi-hit between segments • to do • POSI • Analysis • Residual of chambers for each arm. • HES tracking • Strangeness 2010 in KEK • Preparation

  10. END
