Abstract：
This paper gives the result of proof-of-principle study of a novel compact electron linac. In this linac, the spent beam of a high power klystron, after energy and phase selection by a magnetic field, is used for injection into an accelerator section and the klystron works in self-excited mode-of-operation. According to this proposal, many components of conventional linacs can be omitted to simplify the construction, maintenance and reduce the cost. The realization of this scheme with better affordability should promote the applications of linac.;There are several key problems that should be resolved to realize such a novel linac. The electron bunch properties, such as energy, current, emittance, etc., and the frequency stability of the klystron oscillator have to be appropriate for accelerator application. In this report, computer simulation and experimental measurements are carried out which results confirm the feasibility of the realization of this novel linac.
