Description
Advancements in particle accelerator technology hinge on our ability to precisely measure and understand the behavior of high-brightness beams. Following the installation of the new photo-cathode gun (PCG) laser at the front-end of the Advanced Photon Source (APS) linac, commissioning studies are needed to understand and bring the new PCG beam up to operational standard. In the present work, we present initial measurements characterizing the longitudinal phase-space of the thermionic-cathode gun (TCG) electron beam using a transverse deflecting cavity (TCav) located at the end of the APS linac. Downstream of the TCav, which deflects the beam vertically, lies the B1 horizontal bending magnet and three Chromium Oxide screens placed at three different locations where the beam is intercepted and imaged. Measurements of the TCG beam longitudinal phase-space are discussed and compared to previous measurements of the PCG beam longitudinal phase-space.
