The search for the optimization of some junction parameters to realize a fast particle (radiation) discriminator is discussed. The authors investigate the general aspect of the switching operation in connection with both problems of intrinsic noise and nonequilibrium processes induced by the radiation. The discussion is carried out in terms of an effective radiation flux, namely the flux which produces a number of switchings equal to that produced by intrinsic noise. Such a quantity gives a direct measure of the device performances. The effects of some relevant junction parameters, as the junction area, the Josephson current density and the bath temperature, on the behavior of the effective flux as a function of the response time of the device are presented.
