Tasks March 31, 2009
(1) Flux from NaI -vs- gamma flash
Sum (bin x NaI) -vs- Sum ref
Explore cuts on NaI
NaI runs which need cuts: 43,47,51,55,59,63,73,77,81,85,89,93,97,101,105,109,113,117,121,125,129,133,137,145,149,213
NaI runs, no cuts: 173,178,183,193,198,203,208
Problem runs: 141,163,168,218,223,228,233,239
(2) Where is gamma flash coming from?
For H2O:
MT – empty target runs: 122,123,124 FT – full target runs: 110,111,112,114,115,116 NT – no target runs 118,119,120
Pick runs close in time
FT = a NT + b MT + S
Photons in detector/photons in beam coming from:
(a)room (b)plastic bottle (c)H2O
(3) Same as (2) but for neutron
Hope it is zero
(4) Same as (3) but for D2O
Full target runs: 102,103,104,108,107,106
(5) Gamma flash counts versus number of pulses for D2O and H2O for runs under similar beam conditions
