Comprehensive FNAL Test Beam Performance Evaluation of Detector Modules

This paper outlines the FNAL test beam team’s evaluation of various detector modules under specific operating conditions. Key devices include reference RF modules and n-in-n and n-in-p RR modules. The performance assessment covers electronic metrics such as noise from pedestal and random runs, gain with test pulses, and header analysis. We analyze charge collection efficiency, signal-to-noise ratio, cluster sizes, and resolution based on angle and irradiation levels. This study aims to address gain non-uniformity and cross-talk, with comparisons against simulation data to enhance test accuracy.

  1. Fnal Test Beam Paper Outline The FNAL test beam team

  2. Outline • The devices under test (reference rf module, n-in-n, n-in-p RR modules) • Operating conditions (test beam environment, pixel telescope, temperature…) • Electronic performance [noise from pedestal runs and random runs, gain with test pulses and header] • Landau, signal to noise, cluster size, resolution for rf module as a function of angle (check Landaus for highest angle) • Charge collection efficiency, signal to noise, cluster size, resolution and tracking efficiency for n-in-n and n-in-p • Average fractions of hits for high/low irradiation in n-in-p and n-in-n for good pixel tracks.

  3. Outline continued • Charge collection efficiency as a function of HV (normal incidence only) for reference module and irradiated module [ballistic deficit]. • Remarks: • It would be good that the cluster width reflected charge sharing and not noise [3s inclusion threshold?] • Gain non uniformity needs to be taken out especially for p-type sensor • Comparison with simulation?

  4. Cross talk? • From Karol tp studies of cross talk in beam region with Lars settings
