Purpose

Special meeting to discuss the recovery of Hall C, target arrangements, and ESR testing plans.

Attendance

Creel, Wright, Schleeper, Meekins, Lassiter, Bridza, Fowler, Sun, Kenyon, Meekins

Agenda and Notes

Hall C was not able to operate due to what appears to be a flow obstruction on the 4K supply piping. The transfer line is being warmed to remove the contamination. An RGA will be used to help determine the type of contamination. Only the transfer lines will be warmed, the magnets will be isolated and warming ambiently. There is no apparent cause/source for the contamination.


These event is expected to cause a delay of roughly 1-2 weeks for ESR testing. Due to maintenance requirements on the Hall A target, this target will not be used for the testing. Additional load will be generated at the Hall C target to account for the missing target.
