A method for determination of heavy charged particle energy using the results of acoustic measurements is suggested. To test the method, the energy of protons has been determined at the IHEP I-100 linac with the following parameters: 100±1 MeV particle energy; 1·1010–1,5·1011 sm–2 particle pulse intensity; 0.3–60 μs current pulse length. Determination error for about 100 MeV protons doesn’t exceed 3%.

An experimental facility for study on acoustic properties of solids operating on-line with the Electronica-NTs-80 microcomputer is described. Operating frequency range is 1–400 MHz, temperature range is 4.2–400 K. The accuracy of determination of acoustic wave velocity relative variation is 10–7, wave amplitude is ≲2%. The method of quadratures is used for measuring acoustic wave velocity relative variation, attenuation factor and secondary harmonic.

Avdoshin E.S. «A laser interferometer for measuring acoustic pressure in a gas» Приборы и техника эксперимента, 34, № 4, с. 156-160 (1991)

A design of a light guide acoustic radiometer based on a two-channel optical gas-filled interferometer where laser radiation modulation is performed by acoustic pressure on a gas is described. The accuracy of measuring acoustic pressure in the range 20–15 dB is 0.2%. Interferometer optical elements are combined in a common casing, where the measurement of phase difference of measuring and reference channels is done in case, when membrane vibrations take place due to the acoustic pressure. Practically the radiometer is not susceptible to vibrations.
