	The potential existence of exotic neutrinos beyond the three standard model neutrinos is an important open question in particle physics. IsoDAR is a cyclotron-driven, pure electron-antineutrino source with a well-understood energy spectrum. High statistics of anti-electron neutrinos can be produced by IsoDAR, which, when coupled with an inverse beta decay detector such as the LSC at Yemilab, is capable of addressing observed anomalies attributed to sterile neutrinos at the 5 σ level using electron-flavor disappearance. To achieve this high significance, the IsoDAR cyclotron must produce 10 mA of protons at 60 MeV. This is an order of magnitude more current than any commercially available cyclotron has produced. To achieve this, IsoDAR takes advantage of several innovations in accelerator physics, including the use of H²⁺ and RFQ direct injection, paving the way as a new high power accelerator technology. These high currents also allow for new experiments in dark matter, as well as high production rates of rare isotopes such as Ac225 and Ge68.

The potential existence of exotic neutrinos beyond the three standard model neutrinos is an important open question in particle physics. IsoDAR is a cyclotron-driven, pure electron-antineutrino source with a well-understood energy spectrum. High statistics of anti-electron neutrinos can be produced by IsoDAR, which, when coupled with an inverse beta decay detector such as the LSC at Yemilab, is capable of addressing observed anomalies attributed to sterile neutrinos at the 5 σ level using electron-flavor disappearance. To achieve this high significance, the IsoDAR cyclotron must produce 10 mA of protons at 60 MeV. This is an order of magnitude more current than any commercially available cyclotron has produced. To achieve this, IsoDAR takes advantage of several innovations in accelerator physics, including the use of H²⁺ and RFQ direct injection, paving the way as a new high power accelerator technology. These high currents also allow for new experiments in dark matter, as well as high production rates of rare isotopes such as Ac225 and Ge68.
