[Mott] Mott plan for today

[Joseph Grames]

Mott plan for today, Monday Feb. 10th:

Given the accelerator changed to a shutdown mode we anticipate a slow start up today. Here are our shift plans refined from last week's e-mail:

DAY : 0800-1600
---------------
1. (John/Shukui/Joe) Return Hall C laser rep rate to 31.1875 MHz
2. (Riad) Use 15.59375 MHz trigger to generate 31.1875 MHz phase lock Mott TDC stop pulse
3. (Cryo) Pump down INJ/NL from 4K to 2K

SWING : 1600-2400 (Marty, Riad, Joe)
------------------------------------
1. Lockup INJ/NL to beam permit, recover systems
2. Restore nominal 6.3 MeV setup to FC2 and Mott with 499MHz
3. Optimize 31.1875 MHz bunch vs. bias and chopper to Mott
4. Measure spectra and momentum at 6.3 MeV, scale to KE=5.0 MeV and repeat.
5. Set TDC timing delay - ensures signal and background events occur similarly from each detector package
6. Repeat PMT HV setup - increase and match PMT signal gain following recent repair of down-dE
7. Measure instrumental asymmetries
