We report a new calibration system for large size X-ray optics at ISAS. We adapted a 'dynamical' pencil beam collimated from an X-ray generator, the maximum voltage for which is 50 kV. By combining two stage systems for the X-ray generator and a collimator, the pencil beam dynamically sweeps across a circular region of a telescope with the radius of 60 cm at maximum. In this case, the X-ray telescope and the focal plane detector are both statically fixed. A 4.4~m long rail for detector stage and two positions of the telescope stage provide focal lengths from 4.5 to 12 m, while the previous system can accommodate 4.5 or 4.75 m focal length. The preliminary performance of this system is summarized in this paper. For the post-Astro-EII satellite, a hard X-ray multi-layer supermirror with an unprecedented sensitivity up to 80~keV is strongly expected. This beam facility is of importance because the hard X-ray mirrors always require a long focal length of 8-12 m due to the small reflection angle (about 0.3 degree). Focal length and diameter of future telescopes are always decided by the boundary conditions of the mission at the last moment of the design freeze. Our new X-ray beam facility is designed to match with any kind of X-ray telescope parameters.
