[Halla_running] [New Logentry] RC update

[Jessie Butler]

Jason & All,

Just want to verify, I thought the plan, for the access, is to remove the sieve from LHRS, change LHRS polarity to positive and also install the sieve on RHRS. Please confirm...

Thanks,

RC Update!! 

We were able to complete the extra set of high momentum optics on the Ti target during swing shift. We Followed that up by completing bullseye scan, finishing up early owl. 

For the last few hours of owl shift and in to day shift MCC had an issue with a vacuum chamber and a vertical separator .

The plan for MCC today is to investigate the root of the BLM trips. After their investigation on the Beam loss monitors, they hope to give us an opportunistic entry into the hall. 
For or entry , we plan to remove the sieve from the left arm, and change the polarity of the LHRS magnet. 

We current our experiencing an issue with the raster. Our raster expert has been in contact with MCC and we hope to have the issue addressed soon. And if needed , we can use the hall access to address this further.
