Calibration of X-ray telescope prototypes at PANTER
Abstract
We report on a ground X-ray calibration of two X-ray telescope prototypes at the PANTER X-ray Test Facility, operated by the Max-Planck-Institute for Extraterrestrial Physics, in Neuried, Germany. The X-ray telescope prototypes were developed by the Institute of Precision Optical Engineering (IPOE) of Tongji University, in a conical Wolter-I configuration, using thermal glass slumping technology. Prototype #1 with three layers and Prototype #2 with 21 layers were tested to assess the prototypes’ on-axis imaging performance. The measurement of Prototype #1 indicates a Half Power Diameter (HPD) of 82″ at 1.49 keV. As for Prototype #2, we performed more comprehensive measurements of on-axis angular resolution and effective area at several energies ranging from 0.5-10 keV. The HPD and effective area are 111″ and 39 cm2 at 1.49 keV, respectively, at which energy the on-axis performance of the prototypes is our greatest concern.
