Dispersion in HA line possibly causing FFB issues?

Log Number: 3787193Logbook(s): Entry Makers: kiarraBody: 

Please note, I went through the FFB setup procedure for the hall before coming to this conclusion.

I got FFB running without tripping but couldn't turn RF ON without tripping on IC dump left.
Talked to the software expert, and he explained what indicators to look for in order to troubleshoot...

Problem is not software related, however, the Horizontal BPM tabular data is very noisy... not like the
Vertical which only ranges about +/- 100 microns in the max/min areas. The Horizontal data, on the other
hand, jumps around with high ranges that reach about +/-300microns.

Third time this shift. Manual reset in BSY will restore beam operations for a few minutes then trips again.

Update

All Halls up to current with no ion chamber trips. Only issue now is getting Hall A FFB to work. Getting a "cal fault" and we are unable to clear the fault. Documentation says contact software on call so that's what we're doing.

Had to go to the service building to manually turn on pump. All is good

Masking BSY high power dump node

Log Number: 3787118Logbook(s): Entry Makers: kiarraBody: 

NO beam to HC while out in the field investigating. Going to continue setting up other halls
while one of us goes out into the field to investigate/reset dump faults.
