0126 Series 07101222_2351 stopped at 2nd file. Start a new series 07101223_0122 with the same settings.
0149 Series 07101223_0122 hung at the 2nd file event 26848. Start series 07101223_0150
0240 Series 07101223_0150 hung again because trigger FIFO always read count 0.
0241 Started series 07101223_0239 and display 100% of the traces to make vi run slower. Trigger threshold: DCRC30 G8 = 0xD ADC bins; DCRC33 G9=0x14 ADC bins.
A few debug runs
07101223_0401 with neutron source Trigger threshold: DCRC30 G8=3.5mV (0x17); DCRC33 G9=9mV (0x3b). vi stopped at file 5.
0500 Take background run 07101223_0503 after relocking squids: Trigger threshold: DCRC30 G8=3.5mV (0x17); DCRC33 G9=9mV (0x3b).
0540 Series 07101223_0503 stopped at file 5
0854 Relocking phonon channels on DCRC33 G9. Start neutron shield background run 07101223_0853.
1042 Stop the series 07101223_0853 at file 6.
1053 Start the neutron run with shield on 07101223_1052
1218 Stop 07101223_1052 at file 6
1225 Start 07101223_1224 Ba-133 + Am241 run.
1252 07101223_1224 stopped at file 4
1256 Start 07101223_1256 same settings as 07101223_1224
1405 Stop the run 07101223_1224. Lost one channel.
1424 Set QET bias =-1000uA to all phonon channels and charge bias=0 and take noise psd from labview. Other phonon settings are the same as data taking runs.
1653 1K pot is out of liquid helium. Stop 1K pot and circulation and warm up.
DCRC30 Qi charge noise is larger.
