Abstract
Two detector systems are currently being developed for use with high pressure cells on beamline 9 at Daresbury lab. The first is a television area x-ray camera which is used for rapid alignment and specimen characterization. The second is an imaging plate system which is being developed to obtain accurate integrated intensities from small vol. powder samples. The television detector has been used to det. lattice parameters to an accuracy of 0.001 A. The measured intensities compare well with data from the same specimen collected on film. The imaging plate system was used in the same configuration as the television detector and the film. The specimens studied were La2CuO4 and InSb. The early results from this detector show a great deal of promise esp. in the low photon flux region which is essential for detg. accurate intensities from weak Debye-Scherrer rings. A radial integration program for summing over the whole diffraction range is being developed. [on SciFinder(R)]
