[Xrayops] S:IS1 septum magnet/User Operations Oct. 1st

[APS Experiment Hall X-ray Operations Problem List]

Problem: As of Tuesday evening, the APS has been troubleshooting an issue with injection septum S:IS1 operation.  Machine studies have been cancelled as of the issue origination.



Activity: The ASD Power Supply Group with assistance from the AES/MOM Group have been actively diagnosing the source of the problem.  As of this morning, additional diagnostic tests have resulted in the decision to replace the injection septum magnet assembly.  A spare septum magnet assembly had already been located, electrically tested and confirmed as leak tight and is in the process of confirmatory testing.  Work planning and control efforts are progressing in coordination with HP, Rigging & Lifting, WSH and a host of AES support groups.  The removal/installation time as well as bake-out and demobilization, followed by SR conditioning and start-up, has a low probability, of infringing on the start of user operations on October 1st.



Estimated time of shutter enable: N/A



Next planned update: Recurring updates will be provided, at minimum daily.
