The software tasks to be completed for a successful DIRC commissioning are listed below under several categories. Please contact Justin Stevens if you're able to contribute to one of these activities.
Simulation
-
Implement "as-built" geometry in HDDS xml, including all support structures and material inside the bar boxes (Yunjie/Maria)-
Implement individual bar sizes from spreadsheet provided by Matt
-
-
Add smearing of DIRC truth hits in mcsmear to write out DIRCPmtHit object with time and pixel ID. Include time resolution smearing (Justin)- Add per-pixel efficiency from analysis of PMT module tests, with values eventually coming from CCDB tables (Andrew)
- Add realistic time resolution from PMT module tests (Bill/Justin)
- Add cross talk from analysis of PMT module tests (low-priority)
-
Switch hdgeant4 to using "measured" times in GlueXSensitiveDetectorDIRC, instead of using "time_fixed". Requires similar modification to LUT reconstruction to include flight time of particle relative to other detectors. (Justin)-
A bug was identified in the propagation time by Roman, and Justin submitted an issue to Richard on the HDGeant4 GitHub.
-
-
Add LED generator to hdgeant4/src/GlueXPrimaryGeneratorAction (similar to LUT generator) for developing timing calibration scripts. (Yunjie)
Reconstruction
-
Create DDIRCGeometry to retrieve necessary info from XML: including GetBar(Y) function to return bar ID for extrapolated tracks (Justin)- Add conversion of pixel number to position space (Justin)
-
Add CustomAction to dirc_reactions plugin to split tracks into kinematic bins, and fill histograms of thetaC, likelihood, hit patterns, etc. (Justin)-
Separate tracks by bar, x position (5 cm bins) and momentum (0.5 GeV bins)
-
-
Add DIRCPmtHits to REST format, so they can be used more easily in later analysis stages (Justin)- Studies of size increase for REST files (Justin)
-
Add DIRC hit information to analysis tree PART format (Justin) - Add time imaging reconstruction to libraries/DIRC (Maria)
- Add FastDIRC reconstruction to libraries/DIRC (Cris?/Yunjie)
Data
-
Write DDIRCTDCHit decoder in libraries/DAQ for parsing raw data (David)-
Initial version works pull request, but and has been checked with data
-
-
Write DDIRCTDCDigiHit in libraries/DIRC to be used in TTAB/DTranslationTable.cc to convert hardware ID to pixel ID (Justin) -
Write DDIRCPmtHit_factory in libraries/DIRC to read DDIRCTDCDigiHit, and write out the same object as mcsmear (Justin) -
Write Online and Offline monitoring plugins, and add DIRC to occupancy_online plugin to be run with RootSpy (Justin) - Calibration plugin and scripts for timing offsets from LED data (Yunjie)
- Test with simulation of LED signal generator in hdgeant4
- Include reference time from LED pulser and SiPM monitor (fADC and TDC)
Event Display
- Write class which provides 3D position for pixel from DDIRCPmtHit object which can be used in Thomas's event display (TBD)
- Create database of expected hit patterns for (PID, bar, x position, and momentum). Goal is to superimpose expected pattern histogram behind hits for individual events to see if they match (Roman)
