In general-purpose accelerators, increasing the beam-flux of ions is more difficult than that of electrons, making non destructive diagnostics using the electric field induced by the beam is highly challenging. However, laser-driven ion beams, which have been progressing toward practical application in recent years, exhibit a beam flux approximately 100 times greater over short durations. This substantial increase makes beam diagnostics using induced electric fields increasingly feasible. Against this background, we performed non-destructive ion beams position diagnostics using a beam position monitor (BPM), aiming to support the practical use of high-flux ion beams. In our experiment, a proton beam accelerated by a laser was bunched using a phase-rotation cavity, deflected by a steering magnet, and its position was measured using the BPM. |
