| 内容記述 | We studied feasibility of detection of a gap which is located across a beam track by measuring low-energy (63-68 keV) photons generated by beam irradiation. An experiment was performed with the Heavy Ion Medical Accelerator in Chiba (HIMAC). A C-12 beam having 290 MeV/u was injected on a target consisting of two acrylic blocks. These two blocks were placed with a 10-mm gap along the beam axis. A detection system consisting of a semiconductor detector, a lead collimator having a slit, and borated polyethylene blocks was placed on a movable stage to detect low-energy photons emitted perpendicularly to the beam axis. The position of the detection system was moved at 2-mm intervals along the beam axis. It was found that the yield of 63--68~keV photons was clearly correlated with the position of the detection system. The position at which the yield curve had the lowest value agreed with the gap position. We also confirmed that the experimental result was well reproduced by a Monte Carlo simulation that includes generation of secondary electron bremsstrahlung. | |||||
