Purpose: creation of highly efficient radiation detector for the detection and identification of radionuclides in nuclear energy technologies, safety and ecology. Detector with highly compressed xenon has a high energy distribution and radiation resistance, operates at temperatures up to 200 C. In the performance of the project reasonable task using ionization chambers with xenon high-pressure technology of nuclear power, shows the relevance of issues made the choice of methods of deep cleaning xenon. The design documentation of vacuum electric installations for deep cleaning Xe. Methods for cleaning heternoho Xe nerozpylyuvanymy Heterosexual based on Zr-Al and the method Xe cryogenic purification from impurities inert gases. Made Complete plants for cleaning and filling of xenon detector, which allows the system to receive the first high vacuum (1 ? 10-7 Pa), and then fill high-detector (99,9999%) Xe at a pressure of 60 atm. The installation consists of mahnitorozryadnoho and Turbo-molecular vacuum pumps, all-metal valve chamber cleaning, cryogenic tanks and wastewater pumping xenon. Cleaning when He is in a vacuum chamber, between a titanium cathode and anode triggered vacuum arc discharge and an intensive spraying cathode. Further installation will be used in the industrial manufacture of detectors. Designed and manufactured nitrogen cryostat for cooling and cryogenic pumping xenon. Cryostat temperature detector provides regulation in the range 173-293K and its stabilization with an accuracy of ± 1. Designed and manufactured ionization chamber with xenon high pressure - spectrometric detector of gamma radiation. The size of the detector 107? 380 mm. The purity of the gas inside the detector may simply and reliably measure the shape of the current pulse of gamma rays, determined the lifetime of carriers. Room Xe is considered acceptable when the lifetime of electrons than 2 msec in gas density of 0.5 g / cm3 Later the project created by the installation of cleaning and spectrometric detection He, answering technical problem. The continuation of the work will be the development of portable spectrometers He, software development, testing radiation detectors for spectrometry -radiation dosimetry and neutron fluxes. Keywords: detector, ionization chamber, ionizing radiation, compressed xenon. Product Description popup.authors Антоненко М.І. Давидов Л.М. Леонов С.О. Махненко П.Л. Мельников С.І. Пудов О.О.
