Description
The RF beam sweeper at ATLAS facility plays a key role in the production of radioactive ion beams by enabling time-of-flight-based separation, thereby improving the purity of in-flight rare isotope beams. The current sweeper operates 6 MHz and achieves a maximum deflecting voltage of 55 kV. However, the enhanced beam capabilities introduced by the Argonne In-flight Ion separator (RAISOR) require a more versatile and higher-performance sweeper. To meet these needs, we are developing an upgraded RF sweeper capable of operating at 6 MHz and 12 MHz, with an improved deflecting voltage of 150 kV. The system employs a resonant circuit architecture incorporating electrode plates, an adjustable coil, and a mechanical sliding switch to facilitate frequency adjustment. In this talk, we will present design considerations and fabrication progress of the new RF sweeper, aimed at supporting next-generation rare isotope beam experiments.
