dosimeter of the fast neutrons has a high impact a pin diode to the silicon

摘要

P & this process relates to the adjustment and the improvement of the sensitivity of silicon pin diodes to damage by the fast neutrons. / p & & p & the method consists in selecting a mass based on silicon of the material of type n or p at a high resistivity, having a relatively long period of life of the minority carriers, exceeding 250 microseconds. no, to form the junctions of type n * * * * p + and + and to arrange the mass of the dosimeters, so as to obtain a pin diode to the silicon with a previously chosen from the area bordante to the volume. / p & & p & a dosimeter for personnel to pin diode to the silicon, which is sensitive to a level corresponding to a dose of radiation absorbed as low as 0,1 rads, has a sensitivity of at least 10 mv / rad in the range between 0,1 rads and 10 rads. / p
