Yesterday, Dave Meekins switched the gas in the LAD cell (Loop 3 ) to hydrogen (https://logbooks.jlab.org/entry/4405550)
Beam came back around 7.30pm and we took Harp scans and C-hole run. Everything looked good (see https://logbooks.jlab.org/entry/4405633)
We collected about 6h of hydrogen at 0.6uA during Swing and Owl shift and an additional 1h at 0.3uA.

The vertical separator went down around 5:15am for several hours so no more beam during the owl shift.
As planned, Radcon surveyed the hall at 7:45am but hall went into lockdown due to door problems (https://logbooks.jlab.org/entry/4405976). Therefore the hall is now in restricted access for the SHMS move and GEM repositioning.


Plan for the day:
===============
Move SHMS and HMS to 13.5 degrees 
Decabling, move and cable GEM due to SHMS move
Heidi and technicians work on SHMS vacuum.
=============

=============
We will have our regular RC Meeting today at CH conference Room and via zoom,

Many Thanks to our shift takers for their hard work. We still need shift crews for the weekend Owl shift. Please consider signing up if you are available.
