摘要

本文介绍了ELBE项目超导直线加速器中束荷高达几十pC的束流动力学模拟结果。加速器由一个3+1/2单元特斯拉射频枪和两个9单元特斯拉腔组成。结果表明，将以阴极为中心的半电池的后壁改为圆锥形后壁，可使其横向束束尺寸减小20倍，并使其在加速器出口的发射度降低20倍。

Beam dynamics in RF-gun cavity with a modified first cell

The results of beam dynamics simulation with bunch charges up to a few tens pC in the superconducting linear accelerator for the ELBE project are presented. The accelerator consists of a 3+1/2 TESLA cells RF-gun and two 9-cell TESLA cavities. It is shown that the change of a flat back wall of the half-cell with cathode in its center by a conical back wall results in reduction of transversal bunch sizes and also of its emittance at the accelerator exit by a factor of 20.
