[BTeam] 7S01 BLM trips

[Jay Benesch]

Colleagues,

I did a moderately detailed rad survey of the NE spreader, staying 
outside the rope around MYBBS06.  I provide my conclusions in
https://logbooks.jlab.org/entry/3932262

To summarize: beam is bent upwards less than design in the common 
dipoles.  The 7S ZA and 9S YR are at design.  MYBBS04 was at design 
before it shorted and MYBBS06 was very hot.  The 7S01 BLM is above the 
entrance to MYBBS06 so the trips were appropriate.

Since we don't want to mess with the BCOMs, I suggest steering to 
address the 7S01 BLM trips be confined to the 9S YR and 7S ZA, in that 
order because the beam pipe is cool entering the YR and hot exiting it.

YMMV

Jay
