Time-resolved imaging of electron and positron beams at APS
Characterizations of stored electron beams and more recently positron beams circulating in the Advanced Photon Source (APS) 7-GeV storage ring have been done using optical synchrotron radiation (SR) and x-ray synchrotron radiation (XSR) imaging techniques. Results include the measurement of the bunch length and horizontal beam size versus single-bunch current for both electron and positron beams, observations of multibunch bunch length effects near 100 mA stored beam current, and initial diagnostics of a coupled-bunch instability with 15-minute period. Both the Hamamatsu C5680 dual-sweep streak camera using OSR and a pinhole camera using XSR from a bending magnet source point were utilized. Proposed enhancements to the beamline will also be presented.
