keyword=Target - EPR - 38.8%
6:55am: EPR: during data taking run number 1936/20936
Target position: pol 3he cell
gradient coil current: T = 5.00A, L = -2.00A
1st order fit:
down: freq. shift = -46.84 KHz +/- 2.51 KHz, P = -38.91%+/- 2.08%
up: freq. shift = 46.56 KHz +/- 2.50 KHz, P = 38.67%+/- 2.07%
0th order fit:
down: freq. shift = -46.65 KHz +/- 2.43 KHz, P = -38.75%+/- 2.02%
up: freq. shift = 46.49 KHz +/- 2.55 KHz, P = 38.61%+/- 2.12%
Note:
I am using the average of 0th and 1st order fit of down flips in the title.
Before sweeps I checked the EEL lab logbook again and set both gains to be 1 turn
(based on Lab data) since the current setting cannot be worse anyway. Then with Mod source 1.5Vpp (suggested by Wolfgang yesterday) I did one good sweep. I
am confident about the numbers quoted above.
