软X射线辐射测量

Soft X-ray Radiometry

在软X射线辐射测量中,和光度学一样,光源标准和探测器标准都同时存在,长春光机所八十年代初,研制了真空紫外光谱区的标准光源;近两年研制了软X射线标准探测器稀有气体电离室和传递标准探测器Al_2O_3光二极管。电离室光谱响应的稳定性和重复性好于±2％;光谱辐射绝对定标的不确定度小于±5％。Al_2O_3光二极管光谱响应稳定性好于±2％,数只二极管的一致性好于±6％。

For soft X-ray radiometry source and detector stan- dards are required. Changchun lnstitute of Optics and Fine Mechanics supports a research and development program in the vacuum ultraviolet and soft X-ray region of the spectrum with the goal of providing radiometric source and detector standards for measurement applicat- ions. The primary standard used in these calibrations is a rare gas ionization chamber. Calibrated Al_2O_3 diodes are available as transfer detector standards with a calibration uncertainty of ±6%
