RTM注入器的斩波/聚束系统的目的是在2380 MHz将100keV 5 mA直流电子束斩波成60个/超0/-长脉冲，然后在插入5 MeV注入器直线加速器时将这些束脉冲聚束到10/超0/。这些束流操纵必须在束流的相空间中贡献最小的增量，使得在注入器直线加速器的入口处，横向发射度小于5..pi。嗯--Mrad。对斩波光束的相移测量表明，聚束场足以实现所需的纵向压缩。使用线扫描仪对斩波和聚束光束进行的束流包络测量表明，发射度保持在设计目标之内。
The purpose of the chopper/buncher system for the RTM injector is to chop a 100 keV 5 mA dc electron beam into 60/sup 0/-long pulses at 2380 MHz and then bunch these beam pulses to 10/sup 0/ at insertion into the 5 MeV injector linac. These beam manipulations must contribute a minimum increase in the phase space of the beam such that, at the entrance to the injector linac, the transverse emittance is less than 5..pi.. mm-mrad. Phase-shift measurements on the chopped beam indicate that the bunching fields are sufficient to achieve the required longitudinal compression. Beam envelope measurements, using wire scanners on the chopped and bunched beam, show that the emittance remains within design goals.
