Paper Abstract

A theoretical investigation of the interaction of electrons with the electromagnetic wave in a microwave amplifier indicates that about 50% of the electrons are in fact accelerated in the amplification process. We analyze a system which consists of an amplifier immediately followed by an accelerator. Although we loose part of the electromagnetic power due to the impedance mismatch, the electrons remain bunched and trapped when entering the acceleration section so that the acceleration process is reasonably efficient. The electrons which lost energy in the amplifier section, practically do not participate in the interaction process, since their velocity mismatch is too large. With 1 kA, 0.85 MV electrons and Ez equals 0.6 MV/m at the input, 40.6 cm of amplification and 43.4 cm of acceleration, calculations show that at the output 6% of the electrons have energies between 8 and 16 MV.
