13. 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.

21. 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.
