Hi Carlos,

I should have the target ready by about 1300. Please make sure there is a TO ready to take over.

Due to some poor planning by the RF group, the key people aren't here next week, so the new plan (as of a few minutes ago after texting with Camille) is they are going to push for full current swing shift today!

Thus Carlos please try to get the hall locked up as soon as possible.   (i.e. be sure the Hall is locked up by swing shift if at all possible)

And second, please let accelerator do there tuning and RF as long as they needed this evening.
(i.e. don't bug them putting in targets, etc. until they finish getting the RF and high current beam setup)

Best Wishes,

(will set spectrometers to CaFe initial settings after certification completed)

3) Hall C Fast Raster to be restored by B. Gunning at 10 AM today

4) Hall C Walkthrough by J. Beaufait to be done from ~ 2 - 3 pm today

5) If the above points go smoothly, Hall C to be swept this afternoon

Accelerator Status:
1) Will try to re-establish beam to Hall C starting today

2) Will try to ramp-up to max current (80 uA) on Monday

No need for RC meeting today, unless requested.
