Abstract :
The procedure of calibration of the detector assembly consisting of the two Galileo micro channel plates (MCPs) operated in a Chevron configuration is described. The current gains and the analog particle gains of the MCPs for Xe ions with charge states from q=7+ to q=43+ and ion impact energies to charge state ratios from 2 keV/q to 154 keV/q have been measured. For the investigated range of ion impact energies we have stated that for xenon charge states of q=7+ up to q=15+ the secondary ion-electron emission coefficient is dominated by kinetic emission of electrons. Potential effects start to be visible for charge states above q=151
