论文摘要
近年来,使用快速波形数字化器对有机闪烁体的质子光产率进行了广泛的测量,并且在不同作者报告的值中存在较大的差异。在这封信中,我们解决了数字信号处理的原理,这些原理在进行闪烁光屈服测量时必须考虑这些原理。如果闪烁脉冲的时间形状与沉积的能量无关,则数字化的波形脉冲高度仅与闪烁光的量成正比。由于有机闪烁体中的快速中子相互作用而导致的闪烁脉冲并非如此。因此,测量质子光产率的作者应报告脉冲积分值,并确保积分长度足够长以捕获大多数闪烁光。
The proton light yield of organic scintillators has been measured extensively in recent years using fast waveform digitizers and large discrepancies exist in the values reported by different authors. In this letter, we address principles of digital signal processing that must be considered when conducting scintillator light yield measurements. Digitized waveform pulse height values are only proportional to the amount of scintillation light if the temporal shape of the scintillation pulse is independent of the amount of energy deposited. This is not the case for scintillation pulses resulting from fast neutron interactions in organic scintillators. Authors measuring proton light yield should therefore report pulse integral values and ensure that the integration length is long enough to capture most of the scintillation light.
