Andriyanov Yu.V., Andriyanova O.N., Bagaudinov K.G., Garilevich B.A., Maksimov D.V. «Three-beam generator of acoustic shock-wave pulses» Приборы и техника эксперимента, 40, № 2, с. 123-125 (1997)

A three-beam generator of shock-wave acoustic pulses is described. The generator consists of three plane radiators of electromagnetic type with acoustic focusing lenses. The radiators are located on a general base symmetrically relative to the generator axis and so, thus the axes of acoustic lenses intersect in one point being the geometric focus for each lens. Measurement results of the pressure amplitude distribution of a shock-wave acoustic pulse in the zone of three beams intersection are presented. It is shown that the pressure distribution has plateau-like form. The generator is intended for crushing the kidney and bile gall-stones.
