With this log entry I would like to show that measuring beam with "Picoammeter" is much less noisy than using "ItoV amp" even in tune mode. Hope it helps the setup of the PSS kicker:

First note that in tune mode the readback from Picoammeter should be multiplied by 1/1.5% which is the ratio of CW to tune mode
CW/tune = (1/60)/254uA ~ 1/1.5%

With no beam (gun off) the current in FC1 using ItoV (Fig.1) and Picoammeter (Fig.2) are shown.
