研究了用滤光片法产生50～60 keV的准单色X射线的条件，对输出的X射线进行了数种金属滤光片实验研究，选出合适的滤光片，通过实验对准直器的机械结构进行了确定。采用自行设计委托加工的X射线管、准直器和购买的高压电源，组装成符合实验要求的X射机。该装置输出了50～60 keV能量段的准单色光谱，在料位计上能替代241 Am低能光子源。

A practical approach to produce 50-60 keV quasi-monochromatic X-ray by selection metal filter was studied .The appropriate metal filter was selected after various types of filters were tested . The mechanical structure of the collimator was also determined . According to the experimental requirement , a X-ray machine was assembled with a X-ray tube ,a collimator and an ultrahigh voltage power source .This device generates standard spectrum of quasi-monochromatic X-ray in the energy range of 50-60 keV ,and the X-ray machine can present an appropriate substitution to 241 Am low energy photon source in the traditional level indicator .
