Description
The paper presents the results of stability of the characteristic of overvoltage diodes under the action of neutron and gamma radiation. Nature of this paper is both experimental and theoretical. An original measuring system of extremely low measurement uncertainty was developed for the purpose of recording characteristics. Recording of volt-ampere and volt-ohm characteristics was performed in a completely new way based on the use of a single current pulse (which allows obtaining more reliable results than the methods recommended in the literature based on the use of DC). The obtained results are useful in all areas of engineering practice when there is a danger of simultaneous occurrence of various overvoltages and nuclear radiation. Theoretical interpretation has given some new interpretations of neutron-phonon and photon-phonon interpretations.
