In stereotactic radiosurgery for intracranial lesions, optimization of the dose to the at-risk organs is important to avoid neurological complications. We aimed to quantify the dose to the pyramidal tract (PT) and improve treatment planning for gamma

High-intensity uranium (U) ion beams are successfully provided at the RIKEN RI Beam Factory. We have attempted to extend the lifetime of the charge stripper as the U-beam intensity has increased. An attempt to enlarge the irradiated area using a rota

We have developed a monitoring system dedicated for heavy-ion cyclotrons that incorporates lock-in amplifiers (LIAs) that can measure the beam phase of signals from phase probe with an amplitude of a few hundred nanovolts. We have compared the perfor
