【摘要】 本文对HT-6M托卡马克装置在运行时所产生的X射线剂量、能量进行了测量研究。真空室环表面剂量较大,变化范围:2.3×10~2—1.6×10~4mSV;大厅剂量变化范围(距环表面2m外)O—1.8×10~2mSv。测量表明,X射线的能量是比较宽的连续谱,并且随测量位置和方向的不同而有一定变化。实验估计能量≤500keV的X射线约占85％左右。本文给出的剂量数据为装置正常运行提供了防护和安全评价的依据。更多还原

【Abstract】 This paper is about the study of X-ray dose profile produced by HT-6M Tokamak when in operation .The measurement shows that X-rays have a continuum spectrum covering a rather wide energy range, and the intensities vary with places and directions. The dose on the vacuum vessel is larger and ranges from 2.3×102mSv to 1.6×104 mSv, while the dose outside of the hall two meters from the torus surface is 0-1.8×102mSv. The number of photons with energy below 500 keV is about 85 percent of the total. The data given here provides necessary information of protection and safety estimation for normal operation of a device.更多还原
