摘 要: 12MeV直线感应加速器能够产生能量-12MeV、流强2.2kA的电子束,被传输、聚焦后形成 -4mm的束斑,与轫致辐射靶靶作用来产生高剂量的X光.首先设计了X光探测器,并利用多层吸收拟合法来对X光能谱进行了测量,得到了X光的轫致辐射能谱,X光峰值大约在2MeV,最后对实验结果进行了分析. The 12MeV Linear induction accelerator can generate the pulse electron beam with energy -12MeV and current 2.2kA.The beam is transported and focused onto the bremsstrahlung converter target(Ta) with about 4mm spot to produce high intensive X-ray.The X-ray detector and the multi-layer attenuation method are designed and applied to measure X-ray bremsstrahlung spectrum.The results show that the maximum energy of the X-ray is about 2MeV.The measurement results are also analyzed and discussed.
