X 射线分析用的检测器通常有 Geiger 检测器、正比检测器和 NaI(T1)晶体闪烁检测器等几种。NaI(T1)晶体闪烁检测器是一种性能很好的γ-射线和 X 射线检测器,它具有分辨时间短(0.25μs)、量子计数效率高、较好的能量分辨本领、使用寿命长等优点。虽然由于光电倍增管带来的噪音限制了闪烁检测器对低能量 X 射线的测量范围,但一般而论,直到能量为5KeV 左右(相当于波长大约为2.5(?)左右)的 X 射线,闪烁检测器仍是性能最佳的检
Detectors for X-ray analysis usually include Geiger detectors, proportional detectors and NaI (Tl) crystal scintillation detectors. The NaI (T1) crystal scintillation detector is a very good gamma-ray and X-ray detector with short resolution times (0.25μs), high quantum efficiency, better energy resolution, long lifetime advantage. Although the measurement of the low-energy X-ray by the scintillation detector is limited by the noise generated by the photomultiplier, in general, X-rays of up to about 5 KeV (corresponding to a wavelength of about 2.5 (?)) Blink Detector is still the best performance check
