Multilayer Nested X-Ray Focusing Optical Device
Aiming at the demand on X-ray pulsar navigation and X-ray space communication, the multilayer nested X-ray focusing optical device is developed and tested. Theoretical design of focusing lenses is carried out according to the principle of grazing incidence, and key parameters of the focusing lenses are determined. The materials of focusing lenses and the preparation technologies such as the coating process are discussed. The performance parameters of the focusing lenses are tested respectively under the conditions of visible light and X-ray. The results show that the spot diameter of visible light is 14 mm, the spot diameter of X-ray is 20 mm, and the focusing efficiency is 30.2%. The effective area is 2400 mm2 in a 10 m vacuum pipe when the photon energy is 1.5 keV.
