【Abstract】 The gain versus voltage characteristics of the microchannel plate be studied analytically .″Energy proportionality hypotheses″proposed by Eberhardt is one of the model that gives some inter-esting results,but it did not consider the influence of the inertial energy of secondary electron of theprimary electron colliding with MCP. In this paper,the effects of the first collision on the modelingresults are investigated and a new gain versus voltage formula is obtained which fit the experimentalresults better than reported analytic models,The new models also conclude that the collision numberschange with voltage applied on the MCP,which is different from the conclusion of Eberhardt.更多还原
