| MOPAB046 | Plan for Operating the APS-Upgrade Booster with a Frequency Sweep | 201 |
|
||
| The APS-Upgrade presents several challenging demands to the booster synchrotron. Swap-out injection requires the booster to capture a high charge bunch (up to 17 nC), accelerate it to 6 GeV, and maintain a low emittance at extraction for injection into the storage ring. To accommodate these conflicting demands, the RF frequency will be ramped between injection and extraction. However, the RF cavity tuners will remain static, which means the couplers will need to withstand a high reflected power at extraction. This paper presents a plan for a system that will meet the requirements for injection efficiency, extracted emittance, and equivalent power at the coupler. Results from tracking simulations and beam studies with a frequency ramp will also be shown. | ||

| MOPAB303 | Design of the X-Ray Beam Size Monitor for the Advanced Photon Source Upgrade | 956 |
|

|
Funding: This research used resources of the Advanced Photon Source, operated for the U.S. Department of Energy Office of Science by Argonne National Laboratory under Contract No. DE-AC02-06CH11357. A beam size monitor provides an intuitive display of the status of the beam profile and motion in an accelerator. In the present work, we outline the design of the X-ray electron beam size monitor for the Advanced Photon Source Upgrade. Components and anticipated performance characteristics of the beam size monitor are outlined. |

| THPAB265 | New RF BPM Electronics for the 560 Beam Position Monitors of the APS-U Storage Ring | 4325 |
|
||
| Within the upgrade of the APS storage ring to a multi-bend achromat lattice, 560 RF Beam Position Monitors will be required. The projected beam sizes are below 10 microns in both horizontal and vertical planes, putting stringent requirements on the BPM electronics resolution, long-term stability, beam current dependency, and instrument reproducibility. For the APS-U project, the Libera Brilliance+ instrument has been upgraded in technology and capabilities, including the independent multi-bunch turn-by-turn processing and an improved algorithm to further reduce the crossbar-switch artifacts. More than 140 instruments, equipped with 4 BPM electronics each, are being delivered to Argonne National Laboratory, consisting of the largest scale production for Instrumentation Technologies. In this contribution, the extensive test conditions to which the instruments were exposed and their results will be presented, as well as the beam-based long-term drift measurements with different fill patterns. | ||
