Description
и практически ие зависит от угла фокусировки первичного пучка лучей.and practically it does not depend on the focusing angle of the primary beam of rays.

Степень 1пол 1ризации прошедшего через кристалл излучени быстро растет с повышением давлени и увеличением длины волны, а также с увеличением электрапроводности кристалла . Дл излучени с дли1ной волны большей 15-20 мкм степень пол ризации 100%For a single crystal of a single crystal of a p-type germanium used as an ionizing element with a specific resistance of 0.009 ohm cm and a thickness of 0.121 slg, compressed along the rystallographic axis III with a pressure of 2000-4000 kg / cm. 12-13.5 microns reaches 95-99%, although at room temperature it is noticeably lower. The degree of 1polization of the radiation transmitted through the crystal rapidly increases with increasing pressure and increasing wavelength, as well as increasing the electrical conductivity of the crystal. For radiation with a wavelength greater than 15-20 µm, the degree of polarization is 100%.
