Notes

Construction and installation schedule

This week sent around an updated schedule for the construction and installation of the tagger and photon beam line components, including manpower estimate for each task. One highlight is that the schedule shows stands for several beam line components being constructed in FY09 using contributed university shop time. Time in the UConn shop is tight at the moment, with one machinist out for illness. He is expected to return within 6 weeks, at which point Richard will inquire with the shop about constructing stands for the photon beam line at UConn. It is conceivable that one of the UConn shop members might be willing to be certified as a welder so that the stands might pass safety requirements at Jlab. Major university groups in the experiment have been asked to buy a license for the scheduling software package FastTrack so that we can read and write these schedule files. The design and build contract for the tagger is supposed to go out for bids in January 2010, so getting the documentation together for that bid package is a high priority for the coming months. The sections on construction of the tagging detectors is not yes broken down at the level of detail that will eventually be required. UConn and Catholic U should begin soon to break out the project into tasks and show that they can be completed in the time available and that the required manpower is accounted for.

Progress on the GlueX Photon Beam change request

All of the documentation has been submitted to the management that is required to bring the P3E schedule into line with the plans presented at the Review last November. As far as we know, this has all been approved. New signs of progress have been seen in the direction of getting our Interface Document adopted somehow into the record of the 12 GeV project. We see this as an important step to help prevent communications problem such as the one we saw earlier in the week regarding the tagger quadrupole.

Two issues for discussion

Tagger background simulations

Discriminators for tagging counters

Tagger and Photon Beam Interface drawings

Spring 2009 CHESS run

Plans for beam tests
