| Abstract |
Manufacture of superconducting rotating-gantry for heavy-ion radiotherapy is currently in progress. This rotating gantry can transport heavy ions having 430 MeV/nucleon to an isocenter with irradiation angles of over 0-360 degrees, and enable advanced radiation-therapy. The three-dimensional scanning-irradiation method is performed in this rotating gantry. Therefore, uniformity of magnetic field is quite important since scanned beams traverse through these superconducting magnets before reaching to the isocenter. In the present work, we precisely measured the magnetic-field distributions of the superconducting magnets for the rotating gantry. We used Hall probes to measure the magnetic field. The magnetic-field distributions were determined by measuring Hall voltage, while moving the Hall probes on a rail, which has the same curvature as a center trajectory of beams. The measured-field distributions were compared with calculated distributions with a three-dimensional electromagnetic-field solver, the OPERA-3D code. Furthermore, beam-tracking simulations were performed by using the measured magnetic-field distributions to verify the design of the superconducting magnets.
