  • Table of Kaon LT Physics Status
Item Status Comment
Q2=3.0 W=2.32 x=0.40 theta_Shms=15.18 Completed
Q2=3.0 W=2.32 x=0.40 theta_Shms=18.18 Completed
Q2=3.0 W=2.32 x=0.40 theta_Shms=21.18 Completed Summary plot of all three settings
Q2=2.115 W=2.95 x=0.21 theta_Shms=7.74 LH2 in progress Al done, Took 50 % of the 21K planned on LH2. [1]
Q2=2.115 W=2.95 x=0.21 theta_Shms=10.74 Almost done Al done, for LH2 we got 80 % of the 25 K we were shooting for. We will try to take the rest before 7 am tomorrow. [2]
Q2=2.115 W=2.95 x=0.21 theta_Shms=13.74 Took LH2 (1C, 21K events) and Dummy (1hr) Plos for all data Took about 13.5 hours to get 1C ( at 70uA and 50% eff would get 1.7C)T; 43 % of min goal
