[BTeam] informal rad survey, NE spreader

[Jay Benesch]

See https://logbooks.jlab.org/entry/3606491

Fifth pass beam seems to be the issue.  Hottest spot was 9S beam tube 
touching MQA7S01 from below, 145 mR/hr.   Upstream of that, tube bottoms 
were almost always hotter than tops.  Exception: top of MYR9S05 entrance 
tube through bending field, i.e. still the 9S beam.

We matched with A beam August/September.

Spreadsheet with mps blm voltages attached.  Red NE spreader, blue SW.
