The analysis detailed of processes of the storage and extraction RF-en
erqy on SLED system by the method of scattering matrix is presented. T
he analytical expressions for envelopes of RF-pulses, which are travel
ling to the load and RF-generator are received. The dependence of ampl
ifier RF-power of the system on the function of turing the working fre
quences, a quality factor of cavities, their coefficient of coupling w
ith feeding guides, and on the function of time switching phase, the f
eeding wave and difference phases of waves in guides of cavities is de
fined.
