[Hps] No RC meeting today.

Dear HPS,

As it is Saturday, I am not planning to have our RC meeting this afternoon.

Quick update on the status of the run:

After the Wien filter flip in the injector yesterday for Hall-A ,we had quite a lot of difficulty to get quality beam back for HPS. You can follow the play-by-play in the log book, but this represent a considerable amount of time tuning and re-tuning the beam. We are now doing our final SVT scan. We found that after careful focussing of the beam, we now have a very good beam spot @ ~25µm σy. (https://logbooks.jlab.org/entry/3714167 <https://logbooks.jlab.org/entry/3714167>)  We are about to turn on the SVT and get setup to continue our production running. 

I talked with the PD, and he recognized the difficulty this accelerator change caused us. He told me he will postpone the planned Tuesday’s beam studies, so we will not be going through this again so soon.

Best regards,
	Maurik
