METER OF FLOW RATE OF CHARGED PARTICLES Russian patent published in 1994 - IPC

FIELD: measuring devices. SUBSTANCE: device has first probe having conducting collector and shielding electrode, measuring amplifier, differential amplifier, non-inverting adder, sweep generator and sweep control unit having second probe which has collector and shielding electrode and electrometric repeater. Second probe is identical to first one. First input of amplifier is connected to collector, second input is connected to shielding electrode and output of adder, output of amplifier is connected to first input of amplifier. Second input of amplifier is connected to first input of adder and output of generator, output of amplifier is output of meter. Input of repeater is connected to collector and its output which serves also as output of device is connected to second input of adder and shielding electrode. Implementation of sweep control unit as second probe, which is identical to first one, and repeater with corresponding functional connections has the result in continuous compensation of sweep-voltage bias which is caused by changing potential of reference electrode due to charge of housing of space ship. EFFECT: increased spatiotemporal resolution of meter, its simplified design. 3 dwg
