Action Items
Implementation of TOF trigger into analysis (Simon and Ilya)Simon has implemented the TOF trigger into the simulation. He has added the capability to require a single hit from one plane from the command line. He can work with Ilya to check the performance of the trigger in a more realistic environment.- Set time for future meetings.

Minutes
Attending: Albert, Alex, Andrew, Beni, David, Elton, Ilya, Mark, Rory, Simon
- Previous CPP meeting: Jul 21, 2021
- Announcements
- Action Items
- Discussion: AI for Experimental Controls testing during CPP. See email from David
- We will invite David to a future meeting where time is available for discussion of this topic.
- MWPC Testing (Beni)
- System is working at a basic level. Triggers are being processed. Serguei has been able to see MWPC pulses in the data.
- Still to check are whether the crate is configured to deliver 125 MHz (scintillator) and 250 MHz (MWPC) clocks to each half of the crate
- Check that the look-back window collects full information from both scintillator and MWPC detectors. Current look-back is set to 500 ns (?)
- Beni and Alex will meet tomorrow at 9:00 at the lab to investigate further.
- hdgeant4 updates (Elton)
- Richard has implemented his new generator for e+e- pairs and also mu+mu- pairs.
- At a very basic level, the generator is working. Elton checked that he can generate events with the new configuration.
- There is some checking within MCWrapper (that will be removed) that does not currently allow the use of the 'BHmuons' option, but there is a work-around. Peter Pauli will implement a more permanent solution soon.
- GlueX Data Analysis
- CPP Simulations
- PID + AI (Andrew)
- Andrew, Albert, Simon and Elton met to discuss how to provide Kishan the information he needs for the pi/mu PID work. The following information will be provided in a custom ROOT file:
- track four vectors (ideally one positive, one negative)
- associated shower information in the FCAL. This will include single block hits if not shower is reconstructed (the latter needs Simon's special branch)
- projected track information to the FCAL and the MWPC plane 1.
- all MWPC hits.
- Andrew has developed some code that can produce the ROOT trees. Elton has the fcal_charged plugin that can access most of the needed information. Simon has provided snippets of code that can access other specific information.
- Mark can work with Andrew to merge branches and code into a single program.
- To start, Albert and Andrew will be using tracks generated with the particle gun. Albert has already produced a file with single pions and another with single muons.
- Andrew, Albert, Simon and Elton met to discuss how to provide Kishan the information he needs for the pi/mu PID work. The following information will be provided in a custom ROOT file:
- Other business
- Next meeting
- Next Wed at 9:00 am. Rory will run the meeting.
