| 内容記述 | Design and Manufacture of superconducting rotating gantry for heavy-ion radiotherapy is currently in progress. This rotating-gantry can transport heavy ions having 430 MeV/u to an isocenter with irradiation angles of over 0-360 degrees, and enables advanced radiation therapy. Moreover, it can lead to reduction in positioning time of the patient and further greatly ease patient's burden. To reduce the size and weight of rotating gantry, we designed superconducting magnets that can excite dipole component and quadrupole component independently, and we are advancing production. The three- dimensional scanning irradiation method is performed in this rotating gantry. Therefore, uniformity of magnetic field is required to superconducting bending magnets because irradiation is carried out by using scanned beam transported by bending magnets. In this work, we measured the magnetic field distribution of superconducting magnets precisely. We used Hall effect devices to measure the magnetic field. The magnetic field distribution were deduced by measuring the Hall voltage while moving Hall effects devices on a rail that was along a center trajectory of the magnets. Unexpected quadrupole component was observed in dipole magnetic field. However, the other results are consistent with 3D-calculation, we confirmed that heavy ion radiotherapy using superconducting magnets will be performed without any problems. | |||||
