Calibration layout of SFA and PFA optics in 100m facility The 13 optics of SFA and PFA could be calibrated one by one, checking the profiles of optics and achieving the PSF. The 4-D stage can adjust the direction and position of the optics quickly to the X-ray beam(φ=550mm). Around the focus, the standard spectroscopic detectors and X-ray camera can collect focused X-ray photon. 4-D stage + optics 3-D stage + Standard detectors

Test plan and needed facilities Planed test for X-ray optics and detectors: Thermal cycle, thermal balance Quick check of telescopes before and after vibration Quick check of telescopes before and after thermal cycle Needed facilities for the above test: LN2 background and shroud for thermal cycle and balance If possible, a UV parallel beam can achieve a quick check before and after vibration and thermal cycle A polarized x-ray source is needed for GPD For test and calibration (E<1keV), new crystal is needed If the weight of one telescope is more than 150kg, a larger circle segment (Tip-tilt) is needed. If possible, we can increase the power of X-ray tube to save time.
