Finding Out and Exploration of Two New Equations for Calculating the Dead-time of Neutron Detectors and the Energy of Slow-downed Neutrons

Abstract

One of the most important issues in nuclear science and technology is neutron detection and optimized usage of neutron detectors. The significance of this issue is to the extent that accurate neutron detection is the most desirable issue in nuclear energy engineering including in the area of nuclear reactors. To better design a neutron detector, many items should be taken into account. One of the items is neutron detector dead-time and its calculation. Nowadays, the dead-time of nuclear radiation detectors is among less-discussed objects and it may usually be neglected. In this research, a new equation for calculating the dead-time of neutron detectors has been found out in a way that applying this equation, the dead-time, which is a very significant issue in radiation detection, is calculated as accurately as possible. In addition, in this paper, the equation associated with the energy of a slow-downed incident neutron is specified. By this equation, the energy of an incident neutron that moves across a path undergoes slowing down and deposits its energy is obtained.
