Today is Beam test day. The hall will be open until 13:00 today for work. 
If you need to go into the hall please make sure you inform the shift crew before you go in.
Work that I know of so far:
Techs working on SHMS magnets: (2 keys)
Heidi\Josh Cryo inspection\walk thru: (2 keys)
Julie and grad student working on NPS: (2-3 keys)

As you can see we should be okay on keys.

We have been getting good beam from the accelerator until we had two problems last night.
The first was an issue with the loop 2 target fan. Target expert was called, and Dave Meekins did a remote fix: https://logbooks.jlab.org/entry/4248884 
I'll add a note to this because I have just been called that this fan issue has reappeared this morning, hopefully it can be fixed permanently.

The second was a faulty multiplexer that doesn't read the temperature on the NPS calorimeter. 
Julie made an access at around midnight to attempt a fix, but this was not successful: https://logbooks.jlab.org/entry/4248890
I expect experts will attempt to fix it today, but I have not heard specifics.
