We have developed a single crystal diamond detector and demonstrated that it can be used as a solid ionization chamber to measure the radiation-induced current (RIC) in heavy-ion radiotherapy. Considering the signal-to-noise ratio, this measurement method is expected to be applicable to the measurement of low LET radiation. However, measurements of low LET radiation have not been performed. In this study, we report on the measurement of diagnostic X-rays using a single crystal diamond detector. We also examined characteristics such as energy dependence.
