| 摘 要： | 文中给出了对一个新型紧凑的电子直线加速器(linac)证明原理的研究结果.在该linac中,通过偏转磁场选择特定能量和相位的大功率速调管用毕束流,然后将它们注入到加速节中,同时使速调管工作在自激振荡状态,使传统linac上的许多部件都可以省去.据此建成的linac的结构简单、维护容易、性能良好、造价经济.因此实现这种具有众多优点的新型linac将有助于linac应用的推广.要实现这样的linac有许多关键的问题需要解决.电子束团的性能参量,如能量、电流、发射度,以及速调管自激振荡的频率稳定度等都必须符合加速的要求.文中给出的计算机模拟和实验结果都表明了实现这种新型的linac的可行性

| 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. |
