Method for obtaining proper injection steering into the LAMPF DTL

摘要

A portion of the LAMPF tune-up procedure involves properly steering beam from the 750 keV, low energy beam transport (LEBT) into Tank 1 of the 201.25 MHz drift tube linac (DTL). The previous method relied on a lengthy and somewhat arbitrary search over input beam trajectory parameters to obtain the desired result. A new algorithm is presented which produces a well centered beam in Tank 1 while significantly reducing the amount of time spent on this process.
