keyword=Target Activity Before Production Running
Target is now set to auto flip /20min @ Pol=~58%. Taking production
data.
Time line before taking data:
23:03 2 x Comet Laser Spectrum 2xFAP Spin up start at ~23%
23:09 NMR Field Sweep @ EMPTY -> Pol = 23%
Short After, Bigbite Magnet ramp up to 710A
23:59 NMR Field Sweep @ EMPTY -> Pol = 20(1)%
00:39 NMR Field Sweep @ EMPTY -> Pol = 30(1)%
04:47 NMR Field Sweep @ Ref Cell -> Pol = 48%
07:45 NMR Field Sweep @ He3 -> Pol = ~60%
07:51 NMR Freq Sweep confirm Peak @ 80.8kHz, Phase is correct, Spin
Direction is correct
07:55 It costs two Spin Flip to find out a error in calibration
constant. It's corrected.
07:59 Spin Flip Subsystem Starts.
08:00 First Spin Flip -> Pol. = ~ 57%
