一、引言目前在热释光读出装置中,使用参考光源监视仪器工作状态的变化,并随时进行校正。但在实际工作中,经常观察到仪器的光源读数变化较大。若改变供给光电倍加管的高压以保持光源读数不变,又会出现热释光探测元件的灵敏度发生明显的变化。为了弄清这些变化的原因,有必要了解所用参考光源的稳定性。为了提高测量装置的稳定性,显然应该寻找一种较稳定的参考光源。在已发表的文献中,对热释光读出装置参考光源问题做了一些讨论。我们做
I. INTRODUCTION At present, in thermoluminescence readout devices, the reference light source is used to monitor the working status of the instrument and make corrections at any time. However, in practical work, it is often observed that the light source readings of the instrument vary greatly. If you change the supply of high-voltage photomultiplier to maintain the light source readings, there will be a significant change in the sensitivity of the thermoluminescent detection element. In order to understand the reasons for these changes, it is necessary to understand the stability of the reference light source used. In order to improve the stability of the measuring device, it is clear that you should look for a more stable reference light source. In the published literature, some discussions have been made on the reference light source for a TLL readout. We do it
