<br>
I did a moderately detailed rad survey of the NE spreader, staying <br>
outside the rope around MYBBS06. I provide my conclusions in<br>
<a href="https://logbooks.jlab.org/entry/3932262">https://logbooks.jlab.org/entry/3932262</a><br>
<br>
To summarize: beam is bent upwards less than design in the common <br>
dipoles. The 7S ZA and 9S YR are at design. MYBBS04 was at design <br>
before it shorted and MYBBS06 was very hot. The 7S01 BLM is above the <br>
entrance to MYBBS06 so the trips were appropriate.<br>
<br>
Since we don't want to mess with the BCOMs, I suggest steering to <br>
address the 7S01 BLM trips be confined to the 9S YR and 7S ZA, in that <br>
order because the beam pipe is cool entering the YR and hot exiting it.<br>
<br>
YMMV<br>
<br>
Jay<br>
