A time-dependent non-linear theory is developed for ion channel electron cyclotron maser (ICECM), and the corresponding numerical calculation results are given for the first time. The theoretical analysis shows that the longitudinal plasma wave tends to enhance the energy exchange between the beam and wave. Using the numerical calculation of the self-consistent time evolution of scattering wave growth, the non-linear effect of ion density on the beam-wave interaction efficiency has been studied. The time norm, which must be satisfied in the operation of ICECM, is verified. Taking 6.8 x 10(13) cm(-3) ion density, 1 MV accelerated voltage and 1.5 KA beam current, the present numeric calculation results show that the pulse scattering wave power and the frequency can achieve about 200 MW and 284 G rad/s respectively.
