STATUS OF THE SHORT-PULSE X-RAY PROJECT AT THE ADVANCED PHOTON SOURCE*

The Advanced Photon Source Upgrade (APS-U) Project at Argonne will include generation of short-pulse x-rays based on Zholents ’ deflecting cavity scheme [1]. We have chosen superconducting (SC) cavities in order to have a continuous train of crabbed bunches and flexibility of operating modes. In collaboration with Jefferson Laboratory, we are prototyping and testing a number of single-cell deflecting cavities and associated auxiliary systems with promising initial results. In collaboration with Lawrence Berkeley National Laboratory, we are working to develop state-of-the-art timing, synchronization, and differential rf phase stability systems that are required for the Advanced Photon Source (APS) Short Pulse X-ray (SPX).
