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.
Comments to Response 3 (Approval)
- Email from Patrizia: The main points are summarized in the next two points.
- "...the committee is satisfied with the results of the MWPC tests and therefore they think the CPP/NPP collaboration fulfilled the requirements to pass the ERR."
- The committee encourages us to measure the performance in Hall D: "...the noise level can be different in the hall and therefore the threshold settings that will affect the efficiency. A test of chambers in the hall before the run is advised."
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
