Abstract

We report a ground-based X-ray calibration of the Astro-E2 X-ray telescope at the PANTER test facility. Astro-E2, to be launched in February 2005, has five X-Ray Telescopes (XRTs). Four of them focus on the X-Ray Imaging Spectrometers (XIS) while the other on the X-Ray Spectrometer (XRS). They are designed with a conical approximation of Wolter-I type optics, nested with thin foil mirrors to enhance their throughput. A calibration test of the first Astro-E2 flight XRT for XIS was carried out at the PANTER facility in August 2003. This facility has an 130 meter long diverging beam from X-ray generator to XRT. Owing to the small X-ray spot size of about 2 mm dia., we verified that the focal position of each quadrant unit converged within 10 arcsec. The energy band around Au-M edge structures was scanned with a graphite crystal. The edge energy (Au M5) is consistent with that listed in Henke et al. 1997. Owing to the large area coverage of the PSPC detector which is a spare of the ROSAT satellite, off-axis images including stray lights at large off-axis angle (up to 6 degree) were obtained with a large field of view. We also compared the results with those measured with the parallel pencil beam at ISAS which is in detail reported in our companion paper by Itoh A. et al..
