A new system has been developed for efficient calibration of modern space soft x-ray astronomical telescopes, in particular the x-ray detectors with energy and time resolution. The system provides a large-area (about 1000 cm2 ), highly parallel (±1mrad/24mm), timely and spatially uniform (±5%) beam of x-ray beam. Other special features include a multianode (15 anodes and 17 filters) x-ray source and a narrower pulse (width ≤10 ns) x-ray source. There is a six-axes vacuum turntable that can be used in a wide range with high precision (0.1mm and 0.01°). In this paper, the composition, function and performance of this calibration system will be described in detail.
