Abstract

The x-ray mirror calibration program for the JET-X telescope on spectrum-X has recently been carried out at the 130 m long Panter x-ray beam line of the Max Plank Institute fur Extraterrestriche Physik. The excellent spatial resolution achieved with these mirrors, 15 arcsec half energy width (HEW) at 1.5 keV and 19 arcseconds at 8 keV, has proved to be difficult to measure precisely using previously established calibration methods (involving either slit detectors or the ROSAT PSPC imaging proportional counter). New diagnostic techniques have, therefore, been developed using a CCD imaging camera which utilized newly available x- ray CCD technology. Details of the calibration technique and the performance of the camera are provided and results are compared with those obtained from the slit and PSPC detectors.
