Ohmic contacts were deposited on the opposite surface of the crystal by a silver paste. The postbaking of such contacts in the course of 10 minutes led to reduction of transient resistance. the Innovative Aspects and Main Advantages The suggested detector - avalanche photodiodes of new generation allows recording light of minute intensity. They differ from their analogues according to their small sizes (the size of the working elements area of 9mm2), high sensitivity (106-107 V/Vt) and operation speed. The spectral region of sensitivity is 200-900 nm, working voltage is low-5-10V, threshold of sensitivity is at the level of single photons. The method of obtaining differs from the analogue according to its simplicity and moderate price. Areas of application Medicine: physiotherapy, blood autotransfusion, human solarization; Agriculture: greenhouse and hothouse agrotechnology; Biotechnology: synthesis of D2, D3 vitamins; Astronomy: data accessing about physical processes in nonterrestrial objects capable to irradiate ultraviolet radiation; Material composition and electron structure of elements; Ecology: the problem of ozone hole, detection of environment pollution; Nuclear physics and power engineering: recording nuclear particles with the help of scintillators; Astronavigation and ultraviolet location; Disinfection of water, air, clothes, instruments and food products during long storage and epidemics; Defectoscopy, criminalities, study of art-luminescent analysis due to the ability of luminescent of a series of substances under the effect of UVR. determination science: of substance
