USES OF MICROCHANNEL PLATE INTENSIFIED DETECTORS FOR IMAGING APPLICATIONS IN THE X-RAY, EUV AND VISIBLE WAVELENGTH REGIONS

The Rutherford Appleton Laboratory Photon Counting Detector (RALPCD) h as been refined to meet project requirements for a flexible imaging ar rangement with applications at X-ray, EUV and visible wavelengths. The basic detector design comprises commercially available high gain micr ochannel plate intensifiers fibre optically coupled to CID or CCD came ras, to form a modular detector arrangement with the appropriate RAL d etection and centroiding software. Frames of data from the cameras are detected and centroided in a Transputer or C40 parallel processor arr ay where correction algorithms use look up tables to produce pattern f ree images at high resolution. Data from completed applications are us ed to illustrate the performance and future advances are discussed.
