RF Gradiant ramp of 1L03
Completed the gradient ramp of 1L03. All cavities at their current drive high value with the exception of cavity 4. Cavity 4 is not happy above 11.5. When I try to take it to 12 it trips on CWVF and P1. KMAI is also not happy. That might be where the problem is. When cavity4 goes down it takes 3 with it. As I was posting this entry Cavity 4 made a lie of the last statement. Cavity four tripped on QCHL and P1 (see Figure 4). I'll see if I can keep it on at 11.0.

VWien calibration fit
Data from entry #4469029.
Fit function: f(voltage) = ampl * sin((x * calib) - phase) / 180*pi)
calib = (5.34 +- 0.03) degrees / kV
phase = -0.8 +- 0.2 degrees
ampl = (-34.3 +- 0.1) %
The polarization is ampl / 0.3921 = (87.5 +- 0.3) %.
Will compare the calibration constant with what's in the control system and adjust if necessary.
