A measuring apparatus in the form of a multi-channel amplitude analyzer with a time selector is described. lt measures the intensity, energy, and time of radiation, and is utilized in radioactive sampling. The underground instrument consists of an impulse neutron tube; a radioactive radiation indicator; an electronic control switch operated by synchro-impulses from the neutron tube; and a frequency modulator. A frequency discriminator, a multichannel amplitude analyzer, and a conversion block are placed on the surface. The communication between the bottom and the surface instruments is achieved by means of a single channel teleconmmunication system. A block diagram of the instrument is given. The main circuits of most characteristic units and blocks arc analyzed. An electronic switch consisting of threc cathode repeaters passes through an impulse which appears during a given time interval and stops all remaining impulses, inciuding those that appear during the given interval, but arrive after the first impulse. Protection against the effect of splitting an impulse is provided. Instability of the transfer characteristic of the switch is 1-1.5%, nonlinearity 3-5%. A multichannel amplitude analyzer consisting of shaping blocks, a pre- discrimination, and an impulse sorter with several channel outputs, which have a recording eounting system connected to them is included. The operation of the impulse sorter is described in detail. The circuit of the counting block of the recording system is provided. The counter consists of a solid state binary eounting eircuit with a mechanical counter at the output. The position of the trigger units is fixed by means of indicating lamps connected via polarized relays. (Referativnyy Zhurnal, Automatika i radioelektronika, No. 9, 1961).
