  2. Analytical model of saturation effects Saturation effects in MCP are described by the formulas Ezo, Mo – electric field and a gain for non saturated mode; Io – initial current of photo electrons, Ir – resistance current; τ – relaxation time for induced positive charges. A.Berkin, V.Vasil’ev, Zhurnal Technicheskoi Fiziki, V.78, N2, 2008, pp.127-133.

  3. Electric field variations vs. initial current Field distribution Ez(z,T) Field distribution Ez(L,t)

  4. Gain variations vs. initial current Gain factor for τ=6.e-3 Gain factor for τ=6.e-6

  5. Gain vs. initial current MCP parameters: D=20μm, L/D=40, U=1kV, Mo=1.E6
