Owl shift summary: Miha Mihovilovic (SL), Mitra Shabestari (TO),
Mehdi Meziane (3rd)
===================================================================
EVENTS
16:00 Start of the swing shift. We are taking production
data on 3He target. Polarization is 63.88%.
Polarization of the target is longitudinal.
The current runs are 2425/21331.
17:18 We did a NMR check. The polarization of the target is
62.6% . Doug and Vince also changed T3 prescale
from 3 to 5, and changed the limit for the events
from 5M to 4M.
17:49 Started new HAPPEX run. The new run number is #31393
18:50 Sirish just left and he explained to me that we are not
going to be able to take Compton data tonight.
21:40 The beam was really bad for the last hour. It was
constantly tripping. N_trips = 13.
21:48 We did another NMR measurement. The target polarization is
61.7%.
22:13 Started new HAPPEX run #31394
