1. Tracking performance with the ToF by Nicolas:

 

Used the Arches detector geometry for the tracking performance evaluation. Evaluated the tracking angular resolution w/ and w/o ToF and the ToF related material budgets. For this study, using the ToF basic geometry implemented in GEANT4 simulation. For the material budget evaluation for ToF, using the carbon foam based support structure in the barrel ToF, use the CMS ETL reference for the endcap ToF which include Al support structure and cooling. 

 

Suggest to use the BryceCanyon geometry.

Suggest to draw the angular resolution VS material budgets.

 

Action items:

i) The issue to describe the ToF geometry in the ACTS still exists, will investigate this. 

ii) Will have follow up discussions on the polar angle and azimuthal angle resolution requirements for the PID detectors.

 

2. Energy thresholds and residuals in EICRecon by Beatrice:

 

Update the silicon energy threshold to 5 keV and see no significant changes. For this study, using single pion simulation with momentum from 1 GeV to 10 GeV.

11:00 → 11:20 Tracking performance with the ToF

Speakers: Nicolas Schmidt (Oak Ridge National Laboratory - (US)), Nicolas Schmidt (Oak Ridge National Laboratory)
