- Abstract
- A compact superconducting magnet was constructed for low-energy nuclear physics experiments at the RAON heavyion accelerator facility. Conduction-cooled Helmholtz coils with a radius of 40 cm generate a uniform magnetic field of up to 1.51 T at a current of 71 A. Themagnet has two crossing beam windows that allows the beam to pass either parallel (solenoid mode) or perpendicular (dipole mode) to the field direction. The magnet operates at a ramping rate of 0.01 A/s without quenching and generates a highly uniform magnetic induction within 0.1% of the central value of 1.51 T over the volume of 10 x 10 x 10 cm3 corresponding to the size of an active target time projection chamber. Herein, we report our first excitation test and field mapping results.
