Attending:Elton, Albert, Andrew, Beni, Ilya, Mark, Rory
- Previous CPP meeting: Apr 14, 2021
- Announcements
- Action Items
- CPP and NPP Readiness Review
- Responses to the ERR. This link points to the draft response to the ERR.
- MWPCs (fabrication, testing) (Rory)
- Good progress. Two more sections more.
- Started stringing the 8th (last) MWPC last week, now that students are back on campus
- Elton: We should create single-page summary of MWPC, as was done for all previous GlueX detector systems. See GlueX-doc-2376
- Trigger rates (beam test analysis, expectation with target pulled back) (Ilya)
- Ilya presented new calculations showing that the rates increase by about 15% when the target is retracted from 65 cm (nominal GlueX) to 1 cm.
- He continues to run MC studying the target dependence for the signal.
- Hdgeant4 (initial setup and plan for running simulations) (Beni)
- The orientation of the MWPC wire planes has been implemented. Bugs in the code have been fixed related to incorrect units (mm vs cm). Pull request should fix them.
- The geometry xml files have been created, but not yet loaded into ccdb. The program hangs, but Richard has been notified.
- Mark and Beni will take a look at the program output.
- Analysis (low level reconstruction, monitoring)
- Text has been added to the response to address the committee's concerns
- CDC Coverage of electronics by one crate (Beni)
- MWPC gas system
- A new gas mixing system will be some effort.
- Buying premixed gas might be more straightforward, but carries schedule risk and direct cost.
- Rory estimates that we would consume 1 bottle every 2 days. Experience shows that there is several week delivery time.
- Tracking / extrapolation to MWPCs (Simon)
- No report. Needs working MC.
