虽然在碳离子辐照过程中发现了低于切伦科夫光阈值能量的水的发光，并且可以成像，但时间响应尚未测量，因此与切伦科夫光的区别仍然不清楚。为了澄清这一点，我们测量了低于切伦科夫光阈值的水的发光时间响应，并将其与切伦科夫光的发光时间响应进行了比较。我们使用硅光电倍增管（Si-PM）模块测量了不含切伦科夫光的碳离子照射时水影布拉格峰区域的时间响应。我们还测量了包括切伦科夫光在内的水影浅层的时间响应。在这两个区域，我们测量了碳离子照射产生的光的时间波形，其中清晰地观察到泄漏的涟漪。我们发现布拉格峰和浅水之间的波形没有区别。我们的结果与水的发光和切伦科夫光是由同一机制产生的假设并不矛盾。
Although the luminescence of water at lower energy than the Cerenkov-light threshold during carbon-ion irradiation was found and imaging was possible, the temporal response has not been measured, and so the difference from Cerenkov-light remains unclear. To clarify this point, we measured the temporal response of the luminescence of water at lower energy than the Cerenkov-light threshold and compared it with that of Cerenkov-light. We used silicon photomultiplier (Si-PM) modules to measure the temporal response at the Bragg peak area of a water phantom during irradiation of the carbon ion where the Cerenkov-light was not included. We also measured the temporal response at the shallow depth of the water phantom where the Cerenkov-light was included. In both areas, we measured the temporal waveforms of the light produced by the irradiation of the carbon ions in which the ripples of spills were clearly observed. We found no difference in the waveforms between the Bragg peak and the shallow depths of water. Our results do not contradict the hypothesis that the luminescence of water and Cerenkov-light are produced by the same mechanism.
