Contents
Software Packages and Setup
The software packages required to run DIRC simulation and reconstruction are a part of standard GlueX software deployment:
hdds, halld_recon, halld_sim, hdgeant4, etc.
- For the 2018 commissioning period we are using a branch of these repositories: dirc_commissioning_2018
- Installation instructions and a list of steps to start generating simulation can be found in this README file
Analysis Scripts
- Analysis and calibration scripts should be located in dirc/ directory of hd_utilities
Translation table
- Initial decoder work ongoing by David
LUT algorithm documentation
- Writeup from Maria
Studies
Rough Alignment
- Identify likely mis-alignments and implement in alternative XML geometries as examples
- Try using LUT from "as-built" geometry to see how the mis-alignments affect the commissioning observables
Full Alignment
- Goal: Optimize alignment parameters for positions and angles of all optical components using identified track samples
- Plan to use Bayesian optimization technique with FastDIRC algorithm (Cris)
- Closure test with MC by the end of the year?
- Possible test using sub-samples for alignment procedure and validation
- Align optical box components using tracks from single bar, then test alignment with tracks from other bars
- Align all components using identified pion sample, then test alignment with identified kaon sample
