“…where the distribution weighting factors Besides that, this model can describe the electron number distributions for electron avalanches initiated by short lived radionuclides [27][28][29]32]. Also, it can be applied to electron avalanches in accelerated aging tests [26] and with aging effects correlated to construction materials, surface processes, operational gas gain, gas mixtures and flow rates, gas impurities, etc.…”

The electron avalanche statistics for a single and multielectron initiation and a fixed number of initiating electrons is successfully described by a geometric and a single negative binomial distribution (NBD). However, the number of initiating electrons may have a statistical distribution, either stationary or variable with time. When the emission of initiating electrons is a homogeneous (stationary) and an inhomogeneous (non-stationary) Poisson process, the weighted mixtures of NBDs for electron avalanche statistics are applied and discussed. The proposed statistical model is tested by the means of Monte Carlo simulation of avalanche size distributions when the initial electrons obey Poisson distribution and a good agreement is found.

“…The absolute neutron output and flux density distribution of 14.7-MeV neutrons produced by neutron generators have been studied byElegba et al (B298) and Liberman et al(B299). A rapid sample-transfer system that permits detection of FNAA-induced radionuclides with half-lives as short as 300 ms has been described byB301). The potential for sensitivity improvement by cyclic activation was also investigated.…”
