Screenshot of spectrometer magnet and angle settings for upcoming n-efficiency x>1 500 MeV/c calibration.
We cycled Q2/Q3 on both arms to the recommended values (1600A on left, 1400A/1100A on right, respectively). Regulation is on for all magnets except for right Q3, which we set by hand as follows:
desired momentum/3.14 GeV * 1100 A = current for desired momentum
0.488/3.14*1100 = 170.96 A
Entering this setpoint gives a readback of 170.60
