The Advanced Photon Source (APS), in conjunction with Advanced Electronics Technologies Associates (AET), is developing newly designed thermionic-cathode rf guns to replace our aging (circa 1992) guns. Each of the three third-generation injectors will meet or exceed the present high-performance electron beam of its secondgeneration predecessor. Moreover, the new injector design addresses the historical difficulties of maintenance, reliability, and sparse documentation associated with the previous injectors. Engineering design improvements and required performance of the guns will be presented following a brief examination of the APS secondgeneration guns for comparison.

The rf subsystem for the Advanced Photon Source injector test stand is a totally passive system. Waveguide variable power dividers and phase shifters, which are pressurized with SF6, are used to provide three highpower ports that are independently adjustable in phase and amplitude while maintaining negligible differential phase jitter. Either three independent devices or a device requiring three inputs can be tested at any one time.

At the Advanced Photon Source (APS), a method for beamline construction has been developed that allows the researcher to reconfigure the beamline quickly and easily. This technique has been extensively incorporated into the APS injector test stand [1]. Rather than use a statically designed system, it was decided at the beginning of the project that an approach that emphasized versatility would provide maximum utility. A concise review of similar previous approaches at APS will be explored, followed by a presentation of this method and other possible variations, with a bias toward fabrication, assembly, and operator considerations.
