In the former case we used simultaneously four filters at different places along the film, 6 and 12 μ m Fe and 6 and 12 μ m of Cr, as well as an open channel. We will only present the results from the crystals in the range of 5–13 and 2 – 4 keV. Four crystals were used: pentaerythritol (PET) for the range of 5 – 13 keV, potassium acid phthalate (KAP) for the range of 2 – 4 keV, PET for the range of 3.5 – 5.5 keV, and rubidium acid phthalate (RAP) for the range of 1.5 – 2.5 keV. In front of each film, we placed different wedged filters that attenuated the x rays and provided a fiducial for the wavelength calibration. 7 The recorded x-ray pulse shape followed that of the rising part of the laser pulse with a slightly longer decay time than the laser pulse. In January 2005, we recorded the spectra from gold and iron targets, irradiated by the 1 ns long laser pulse of the Omega laser facility, 6 using a spectrometer with four bent crystals called the Henway spectrometer. It has also been used in microradiograpy of biological samples using 350 keV Faxitron sources. It is used mainly for high-energy x-ray radiography, but not intended for use below 10 keV. 4 The AGFA Structurix D7 film (now fro General Electric Inspection Technology, 50 Industrial Park Road, Lewinstown, PA 17044) is a relatively fast, double-side coated, very fine grain film with high contrast intended for industrial use with and without lead screens. 3 The present article describes tests comparing different films with DEF, especially the AGFA-D7 film, which has been used previously in recording diffraction spectra. 2 Previous efforts at looking for different films have also been superceded by the discontinuation of the tested AGFA and CEA-Reflex25 film. Some previous work measured the relative sensitivity of Biomax-MS, XAR, and other films. We have searched for a replacement sensitive to x rays with energies below 10 keV, where the film is most useful for imaging at the current ICF facilities. Aged DEF produces higher background, and may invalidate the absolute calibration. 1 Now, the film is being discontinued, and the remaining lots of it are getting old. The detector of choice for many years has been the direct exposure film (DEF), manufactured by Kodak (Eastman Kodak, Rochester, NY 14650), due to its relative sensitivity, availability, and its absolute calibration by Henke et al.

It is a quick and simple method to determine the life expectancy of processed films and warns of poorly fixed and/or washed films. The Structurix Thio Test Kit also correlates perfectly with other international standards (ISO/ANSI) for determining the archival quality of industrial x-ray film. One dropper bottle of Thio Test reagent of 35mm (about 1,000 drops) Key Advantages: This kit contains the Thio Test colour stepwedge with four steps, which relate to the archivability expressed in number of years. The Structurix Thio Test provides the means for performing the control of fixing and washing as described in EN 584-2 and ISO 11699-2. The AGFA Archival Test Kit is used to perform an archivability check on processed X-Ray Film by measuring the residual thiosulphate in the emulsion layers.
