Abstract: The linac-base neutron source “iBNCT” developed by the Tsukuba team has begun to generate a large intensity of neutrons. To confirm the applicability of the device to BNCT, several characteristic measurements have been implemented. In a water phantom experiment, when the accelerator was operated with an average current of 1.4 mA, the maximum thermal neutron flux was approximately 7.8 × 108 (n/cm2/s). Results demonstrate the stability of the linac over time, showing its promising potential for future patient treatment.
