VDC High Rate Analysis

From APEXwiki

Group: Ole Hansen (leader), Michael Paolone, Seamus Riordan, Guy Ron

Priority Tasks

1) Modify VDC track reconstruction software to handle events with multiple tracks

 (a) Implement a 3-parameter fit routine for VDC clusters to obtain cluster time
     offset t_0 (Michael Paolone) Status
 (b) Modify U-V cluster matching code to exploit t_0 correlations (Ole Hansen)

2) Simulations

 (a) Adapt existing "VDCsim" toy Monte Carlo to APEX conditions (NN)
 (b) Test code modifications with VDCsim-generated tracks (all)

3) Analyze available 0.5 MHz data (all)

4) Prepare for online analysis

 (a) Write/retrieve scripts for VDC reference time calibration (Nilanga?/Seamus)
 (b) Develop procedure and write script to re-calibrate time-to-distance
     relation with lower chamber high voltage (Seamus)

Optional, for offline analysis

1) Optimize tracking efficiency

  (a) Modify cluster finding code (or a different relevant part of the tracking code)
      to handle overlapping (partially "corrupt") clusters (Ole, Guy?)
  (b) [additional items TBD]
