Response 2
- MWPC Efficiency
- Schedule Status
- CPP-NPP Schedule Status 5/11/2021. The following two references show that the new hdgeant4 simulation is operational and working:
- Log Entry 3876633 Histogram of muon hits from hdgeant4 simulation.
- Tracking / extrapolation to MWPCs Preliminary studies of extrapolation of FDC tracks to MWPCs
Comments to Response 2
Response 3
We have summarized the preliminary results from the cosmic-ray test in EEL126 in Production Testing of MWPCs for CPP (GlueX-doc-5373). The CPP experiment requires six MWPCs and we have six chambers that deliver excellent performance in the cosmic-ray setup in the EEL. The estimates of the efficiency are of the order of 99.7% or greater over a broad range of voltage and/or software thresholds. Two spare MWPCs (Frodo and Galadriel) exhibit low levels of electronic noise that is under investigation.

Additions to Standard Equipment
The major modifications required to operate the experiment are the following
- Design, fabrication and installation of the muon detector
- Multi-wire proportional chambers
- Modifications to the downstream platform, support structure and iron absorbers
- New (mono-isotopic) solid Pb target
- Charged-particle trigger based on the time-of-flight detectors
- Move tagger microscope to cover 6 GeV coherent peak
