New method of analysis of charged particle fluxes characteristics in a transverse magnetic field

A new method is suggested that permits to simultaneously measure the energy, W and incidence angle, α of sufficiently fast charged particles moving in a plane perpendicular to the magnetic field in a wide range of W and α values. Operation principles of A1 and A2 analyzing systems used for measurements are presented. The growth of anode voltage, Vsub(a) from the threshold value Vsub(an) to the voltage, Vsub(am), at which the break of anodic current takes place is found to bring about a monotonous increase in Wsub(B)(Vsub(a)) and αsub(B)(Usub(a)), with the Wsub(B) varying within the 200 < or approximately Wsub(B) < or approximately 1200 eV range and at the αsub(B) variation approximately from 10 to 35 deg. The measurements are taken within the magnetic field ranging as 0.08 <= B < = 0.15 tl. The data obtained are of interest for understanding of operating conditions for secondary emission cathodes in devices with crossed fields. The method of measurements is simple, possesses high resolution and can be applied for the diagnostics of processes in the spatial charge of a wide range of electronic devices
