Sadly, we didn't enjoy much beam delivered, practically nothing. At 16:46, the Hall A/C beam dump system went down due to a broken compressor. The beam into both halls is down since them.

Although, we couldn't complete the H2 measurements as scheduled, we decided to continue with the plan scheduled. Dave M. got a fast access yesterday to vaporize and warm the target. 

After consulting Dave, and requesting more info from the Crew Chief, I put Owl shift TO and SL in stand-by in the eventuallity of beam coming back during the night.

At the moment of this report, we are in Controlled Access. Magnets crew are accessing the HMS Q2 issue, and Dave M. is setting the target to D2. 

The plan, after cooling back the target, beam checkout, is having production with D2. 


SHIFT SUMMARIES:

SWING -> https://logbooks.jlab.org/entry/4375784
OWL -> no shift

RUN PLAN:
With D2 target cooled down, beam checkout, and production. 

RC LESSONS LEARNED:
- make a logentry, if plan to leave the CH without crew, even Crew Chief was notified
- do not rely on the word of who contacted RadCon for support, always get direct information from RadCon.

Fun Fact of the day:
Real pasta carbonara consists on guanciale (pork jawl) cut in small pieces and cooked in its own fat, a sauce made of pecorino romano cheese mixed with eggs (as many depending of the quatity) and pepper. Once the pasta is cooked 'al dente', it is moved to the pan where the guanciale was cooked, and inmediately is added the cheese sauce, mixing faster to have a creamy sauce. Add more pepper at the end. DO NOT ADD ANYTHING ELSE!
