Electron cooler current

The current measurement for the collector in the ElectronCooler is capable to operate in HV conditions. The signals can be read out either as sampled transscript or encoded as a frequency signal for a 0-80 mA range, The measurement range could also be reconfigured in software. Between f_min and f_max, the relation of current to frequency is linear. The input isolation voltage is 3 kV.

Current	Signal
0 mA	fmin = 100 kHz
80 mA	fmax = 900 kHz
