摘要
这些加速器将被用于制造快速偶极子和四极子，它们由急剧上升时间脉冲驱动，为高电流kA电子束提供精确的光束操纵。该技术将用于LANL的DARHT直线加速器的2/sup和/ axis。它将用于提供4个脉冲宽度高达120秒的微脉冲。从2 /spl mu/sec中选择。， 2 kA, 20 MeV巨脉冲。快速脉冲将具有调幅能力，以补偿波束诱导的转向效应和其他缓慢的波束质心运动，使其在踢脚器系统的带宽范围内。从理论推导出的比例定律将与在试验台ETA-II上获得的大量实验数据一起提出。
Precision fast kickers for kiloampere electron beams
These kickers will be used to make fast dipoles and quadrupoles which are driven by sharp risetime pulsers to provide precision beam manipulation for high current kA electron beams. This technology will be used on the 2/sup nd/ axis of the DARHT linac at LANL. It will be used to provide 4 micropulses of pulse width up to 120 nsec. Selected from a 2 /spl mu/sec., 2 kA, 20 MeV macropulse. The fast pulsers will have amplitude modulation capability to compensate for beam-induced steering effects and other slow beam centroid motion to within the bandwidth of the kicker system. Scaling laws derived from theory will be presented along with extensive experimental data obtained on the test bed ETA-II.
