IsoDAR@Yemilab: Preliminary Design Report -- Volume I: Cyclotron Driver

Published 9 Apr 2024 in physics.acc-ph and hep-ex | (2404.06281v3)

Abstract: This Preliminary Design Report (PDR) describes the IsoDAR electron-antineutrino source in two volumes which are mostly site-independent and describe the cyclotron driver, providing a 10 mA proton beam, and the medium energy beam transport line and target, respectively. The IsoDAR driver and target will produce a mole of electron-antineutrinos over the course of five years. Paired with a kton-scale liquid scintillator detector, it will enable an impressive particle physics program including searches for new symmetries, new interactions and new particles. Here in Volume I, we describe the driver, which includes the ion source, low energy beam transport, and cyclotron. The latter features radiofrequency quadrupole (RFQ) direct axial injection and represents the first accelerator purpose-built to make use of so-called vortex motion.
