Study of a Special System for Measuring Low-Energy Particle Fluxes

An electronic system for the control of the output cwrrent of a windowless electron multiplier destined for the measurement of low-energy electron and proton fluxes is described. Having established the equations representing the static operation, in the cases of current and voltage reference sources, the general structural organization in which the studied submodule is integrated is discussed. Justification for the choice of the low-voltage components is given. High-voltage insulation, system stability, and estimation of the catalectic failure probability theory is included.
