[Back to Panter's main Page]    SWIFT XRT at the PANTER Test Facility

In July 2000 the performance of the mirror system of the X-ray telescope 
for the mission SWIFT has been studied at the PANTER test facility.

In September 2002, an end-to-end test for the entire X-ray instrument 
of SWIFT is performed at the PANTER test facility.
Three weeks of calibration will concentrate on the following measurements:

  • Focus check
  • PSF calibration
  • Measurement of the effective area
  • Verification of the operating modes of the instrument

  • SWIFT Multi Mirror (left)  vs.  XMM Multi Mirror FM5 (right) inside the PANTER vacuum chamber.
    In the background the aperture (diameter 1 m) of the 130 m long test tube of the facility is visible.

    Closer look at the SWIFT Multi Mirror.

    Effective Area of the SWIFT Multi Mirror in the energy range from 2.0 – 10. keV. Around the gold edge (2.2 – 3.0 keV) measurements at every 50 eV where taken. Beyond 3.0 keV the stepwidth was 500 eV. 
    To simulate nearly parallel X-ray condition (infinite source distance) only one of the 12 sectors of the mirror system was left open, while the other 11 were closed by a stop. The free sector was than brought on the optical axis of the facility.
