Abstract

We calibrated the sensitivities (in A.W⁻¹) of two commercial photodiodes by using an electrical-substitution radiometer in a large X-ray energy range from 3 to 60 keV. These two photodiodes appear to have complementary sensitivity domains. We also propose a new setup of a photodiode aided by a YAG:Ce scintillator. This setup gave a better homogeneity of the response function, making the detector less sensitive to misalignment and we found a modest, but nevertheless, nearly constant sensitivity over the whole energy range.

闪烁体耦合光电二极管灵敏度的高能x射线绝对校准

我们使用电替代辐射计在3至60 keV的大x射线能量范围内校准了两个商用光电二极管的灵敏度（在A.W−1）。这两个光电二极管似乎具有互补的灵敏度域。我们还提出了一种由YAG:Ce闪烁体辅助的光电二极管的新装置。这种设置使响应函数具有更好的均匀性，使探测器对校准不那么敏感，并且我们发现在整个能量范围内灵敏度不大，但几乎是恒定的。

期刊介绍： Section A of Nuclear Instruments and Methods in Physics Research publishes papers on design, manufacturing and performance of scientific instruments with an emphasis on large scale facilities. This includes the development of particle accelerators, ion sources, beam transport systems and target arrangements as well as the use of secondary phenomena such as synchrotron radiation and free electron lasers. It also includes all types of instrumentation for the detection and spectrometry of radiations from high energy processes and nuclear decays, as well as instrumentation for experiments at nuclear reactors. Specialized electronics for nuclear and other types of spectrometry as well as computerization of measurements and control systems in this area also find their place in the A section. Theoretical as well as experimental papers are accepted.
