Abstract

A semiconductor body contains microscopic passages in which multiplication of the free electrons appearing at the entrances to said passages, under the effect of the incident (arrow) ionizing radiation, takes place. In the drawing, the reference 2 signifies the conductive film forming a surface barrier in conjunction with the semiconductor body which is endowed with the property of secondary emission with an emission coefficient better than unity; V.sub.o signifies the voltage applied to the terminals of said barrier; 5 and 6 designate the electron collector.
