摘要
利用均匀线聚焦激光产生的等离子体和软X针孔透射光栅谱仪获得了均匀的线状软X光单色光源.在这一光源基础上,利用加阶梯膜的新方法首次标定了国产无保护层5F软X光胶片在软X光波段的响应特性.
A uniform linear monochromatic soft X-ray source is created by combining a X-ray pinhole transmission grating spectrometer with a uniform line-fooused laser produced plasma. As an application of such X-ray source, a new method is described for calibration of X-ray photographic film that the response of film density versus relative exposure is provided by a step wedge filter foil of known thickness and transmissivity at a given wavelength. Based on this method, the 5F X-ray film is calibrated for the first time in the soft X-ray rogion.
