Abstract : The device consists of two screened sieve-shutters placed in the inner cavity of a cylindrical intake attachment at a definite distance one from the other and perpendicular to its axis. The sieve-shutters are intended for measuring the speed of the the drift of the charged particles by which afterwards there is calculated the mobility of these particles. The sieve-screens are intended for screening the effect of the electrical fields inside of the intake attachment on the outer medium and form a uniform electrical field in the area to be analyzed. The sieve-shutters represent tungsten filament-electrodes onto which there passes an alternating voltage creating a transverse electrical field attracting to itself electrons and ions in the course of all the time except moments of the passing through of a curve of alternating voltage, through a tension which is zero with relation to a given point of space. The sieve-shutters are connected up to a generator of AC, the frequency of which changes periodically with the aid of the commutator of frequency. On the bottom of the intake attachment there is fastened the collector, which catches the charged particles after they have passed through the two sieve-shutters. The ion flux is recorded by the electrometer, to the output of which there is connected the radio transmitter, which transmits to the earth the indications of the electrometer.
