Abstract

A collaboration has been formed between FNAL, UCLA, LNFN Milano, the University of Rochester, and DESY to develop the technology of an RF photoinjector, followed by a superconducting cavity, to produce high bunch charge (8 nC) with low normalized emittance (<20 mm mrad) in bunch spacing trains of 800 bunches separated by /spl mu/s. The activities of bunch charge the collaboration fall into two categories: 1. the development of Injector II for the TeSLA/TTF accelerator. This photoinjector (TTF RF Gun) was tested at Fermilab in September and October 1998 and installed at DESY in November 1998. 2. the installation at the A0 Hall of Fermilab of a modified version of the TTF photoinjector, for photoinjector R&D and to study novel applications of high-brightness, pulsed electron beams. This photoinjector (A0 RF Gun) produced its first beam in March 1999. This paper presents a summary of the tests done at Fermilab on the TITF Injector II and the first results obtained on the new Fermilab photoinjector.

费米实验室高亮度射频光注入器的初步结果

FNAL, UCLA, LNFN Milano, Rochester大学和DESY之间形成了合作，开发射频光注入技术，然后是超导腔，在束间距为800束/spl mu/s的束间距序列中产生高束电荷(8 nC)，具有低归一化发射度(<20 mm mrad)。群控协作的活动分为两类:1.群控协作;特斯拉/TTF加速器II喷油器的开发。该光注入器(TTF RF枪)于1998年9月和10月在费米实验室进行了测试，并于1998年11月安装在DESY。2. 在费米实验室A0大厅安装一个改进版的TTF光注入器，用于光注入器的研发和研究高亮度脉冲电子束的新应用。这个光注入器(A0 RF枪)在1999年3月产生了它的第一束光束。本文概述了在费米实验室对TITF注入器II进行的测试和在新的费米实验室光注入器上获得的初步结果。
