We completed the 3-pass run plan with everything except for the delta scan. 

We had a very productive (and active) day and swing shift yesterday executing the H(e,e')p singles part of the run plan. During owl shift, we experienced pretty much near constant down time due to the inability to ramp, rotate, and control magnets from the counting house. We did have the vacuum turbo pump downstream of the target kick off during this, and Larry was able to come in and reset it very quickly and without issue (big thanks, Larry!). As a last ditch effort, Steve Lassiter was able to control the magnet GUI remotely, and ramped our magnets and rotated the spectrometers so we could at least take a repeat Heep coin 2 setting with the Al dummy target. Dave Gaskell took a quick look at the charge normalized yields on the Al dummy from both before and after the operational restriction, but it does not seem that we can conclusively see an effect https://logbooks.jlab.org/entry/3939864. 

We will meet today at 10am: https://hallcweb.jlab.org/wiki/index.php/RC_Meeting,_Wednesday,_November_10,_2021
