Using the external proton beam of the accelerator at the Institute of Theoretical and Experimental Physics (ITEP), an experiment was performed on recording the acoustic signals accompanying the moderation (up to termination) of an intense proton beam with an energy of up to 200 MeV in water. The signals are damped quasi-periodic oscillations, whose initial period reflects the features of the radiating system. Parameters of the acoustic signal are measured in a wide range of energy release (from 10¹⁶ to 1.2·10¹⁹ eV) for three values of the beam diameter.

The apparatus permits to measure the electromagnetic (EMR) and acoustic (AR) radiations during uninterrupted prolonged measurements when simulating the processes of fractures for rock samples. It ensures the EMR and AR energy spectra determination and their combined processing in such main parameters as signal energy and number of signal, mean signal energy and energy release. The apparatus allows to obtain a new prognostic parameter of rock fracture, determined as the ratio of total energies of EMR and AR.

The developed filters based on acoustic waves was designed for operating in radioreceiver input circuits in the range of short and ultra-short waves, in portable and moving receivers-transmitters, frequency synthesizers, intermediate frequency tracts of domestic receivers. The specific feature of filters was the receiving of active input impedances in transmission band without using matching LC-components. It was reached by selection for piezoelectric prescribed section of certain number of electrode couples in input and output converters.

The seismoacoustic hydrophysical complex intended for investigation of the interaction of geospheres wave fields in a frequency range from 1 μHz to 1 Hz is described. The complex consists of a shorebased system of laser strain meters, laser nanobarograph, bottom station with a hydrophone and a temperature-sensitive element, weather station, and seismoacoustic radiator. The use of modern laser-interferometry methods provided a deformation sensitivity of ≈10^–10 and an atmospheric-pressure sensitivity of 10 mPa.

The circuit for the amplifier with output power exceeding the power delivered to separate transistors was described. It was possible due to the application of superbroadband adder. The specifications of the amplifier were the following ones: working frequency range 150 kHz–230 MHz; amplification factor 45 DB; output power 25 W; power demand 250 W. To provide the optimum load impedance of channel amplifier output transistors the transformers with transformation factor 1:4 were connected between channel amplifiers outputs and adder.
