Abstract
An electron photo-injector facility has been constructed at Fermilab for the purpose of providing a 14-18 MeV electron beam with high charge per bunch (8 nC), short bunch length (1 mm RMS), and small transverse emittance. The facility was used to commission a second-generation photo-cathode RF gun for the TESLA Test Facility (TTF) Linac at DESY; in the future, the Fermilab electron beam will be used for R and D in bunch length compression, beam diagnostics, and new acceleration techniques. Acceleration beyond 4 MeV is provided by a 9-cell superconducting cavity. The cavity also provides a longitudinal position-momentum correlation for subsequent bunch length compression. We report on the RF tests and a first beam test of this cavity.
在费米实验室建立了一个电子光注入装置,目的是提供14-18 MeV的电子束,每束高电荷(8nc),束长短(1 mm RMS),横向发射度小。该设施用于为DESY的特斯拉测试设施(TTF)直线加速器调试第二代光电阴极射频枪;在未来,费米实验室电子束将用于束长压缩、束诊断和新的加速技术的研发。超过4兆电子伏的加速度由一个9单元超导腔提供。该空腔还为随后的束长压缩提供了纵向位置-动量关联。我们报告了该腔的射频测试和第一束测试。
