Description

The IsoDAR experiment aims to deliver a high-intensity neutrino source for precision measurements in neutrino physics. Central to this effort is the development of a compact, high-current cyclotron capable of accelerating H₂⁺ ions to 60 MeV/amu. This presentation provides a status update on the cyclotron’s development, covering key aspects of its radiofrequency (RF) systems, magnetic configuration and mechanical design.
A major innovation in the IsoDAR injector is the implementation of a novel Radio Frequency Quadrupole (RFQ) inserted into the cyclotron for direct axial injection. We also present the latest details on a smaller cyclotron, designed to match as closely as possible the magnetic and electric fields of the larger cy- clotron, up to 1.5 MeV/amu. This smaller cyclotron will be used to test and validate the injection system and first turns of acceleration. The presentation will conclude with an outlook on upcoming integration tests and commissioning plans.
