Abstract :
The Advanced Photon Source´s (APS´s) primary and backup injector sources consist of two thermionic-cathode rf guns. These are being upgraded to provide enhanced and more consistent performance, improve ease of maintenance, and reduce the downtime required to repair or replace a failed injector. As part of the upgrade process an injector test stand is being prepared. The stand will be effectively independent of the APS linac and will allow for complete characterization and validation of an injector before its installation. Multiple high-power rf ports, several types of cathode drive lasers, and a flexible suite of magnets and diagnostics will support testing and characterization of new beam sources as well as the APS injector guns. The ready accessibility of the test stand and independence from the main APS linac will also allow beam-based testing and validation of new or replacement diagnostics before their installation into the APS linac line
