介绍了一种真空紫外辐射强度仪的研制。仪器选用ＭｇＦ２做窗口材料，使用的光电管为ＣｕＩ光电阴极（以ＫＩ和Ｃｕ为原料通过电化学方法制备）。仪器具有良好的灵敏度和重现性，对于ｘ＝４３μＡ的光电流测定１１次，ＲＳＤ＝２．１％，线性相关系数ｒ为０．９９。光谱响应范围１１０～２００ｎｍ。
The development of a vacuum ultraviolet radiation intensity meter is introduced. The instrument uses MgF2 as the window material, and the photocell used is a CuI photocathode (electrochemically prepared from KI and Cu). The instrument has good sensitivity and reproducibility, with 11 determinations of photocurrent at x = 43μA, RSD = 2.1% and linear correlation coefficient r of 0.99. Spectral response range 110 ~ 200nm.
