keyword=Pockels Cell Voltage
We are seeing a stable 680. ppm asymmetry in beam current in Hall A.
I have corrected the high voltage settings on the Pockels cell to zero it.
Given that the correction is ~-75 ppm / HV unit that's a 9 units correction:
Old value New value
Left 639 ->648
Rigth 623 ->614
After that change, the asymmetry has been measured to be A=-37+/-24 ppm.
