Abstract

1. Устройство для измерений профиля поглощенной энергии в образце материала при облучении ионизирующим излучением импульсного источника наносекундной длительности, содержащее широкополосный пьезопреобразователь с высоким временным разрешением, зашунтированный дифференцирующим сопротивлением, отличающееся тем, что, с целью расширения эксплуатационных возможностей, оно снабжено твердым акустическим угловым волноводом с отражающей поверхностью и защитным экраном, при этом акустический угловой волновод размещен между защитным экраном и пьезопреобразователем и выполнен в виде призмы из материала, в котором величина механических напряжений при поглощении энергии импульсного ионизирующего излучения много меньше напряжения, возникающего в образце, установленном между экраном и волноводом, а защитный экран выполнен с отверстием для прохождения излучения, причем пьезопреобразователь установлен на выходной поверхности волновода.2. Устройство по п.1, отличающееся тем, что отражающая поверхность твердого акустического углового волновода выполнена под углом 45по отношению к входной поверхности.3. Устройство по п.1, отличающееся тем, что акустический волновод выполнен из плавленого кварца.1. Device for measuring the absorbed energy profile in a sample of material when irradiated with ionizing radiation of a pulsed nanosecond source, containing a broadband piezoelectric transducer with high temporal resolution, shunted by differential resistance, characterized in that it has a solid acoustic angular waveguide with a reflective surface and a protective screen, while the acoustic angular waveguide is placed between the protective screen ohm and piezoelectric transducer and made in the form of a prism from a material in which the magnitude of mechanical stresses when absorbing the energy of pulsed ionizing radiation is much less than the voltage arising in the sample installed between the screen and the waveguide, and the protective screen is made with a hole for the passage of radiation, and output surface of the waveguide. The device according to claim 1, characterized in that the reflecting surface of the solid acoustic angular waveguide is made at an angle of 45 with respect to the input surface. The device according to claim 1, characterized in that the acoustic waveguide is made of fused silica.
