Paper Abstract

K-B microscope intended for the use in inertial confinement fusion experiments was designed. The microscope operates at the 8keV x-ray energy and provides the 8X magnification. The parameters of the microscope are decided by requirements of ICF experiments. Ray tracing software (Zemax) is used to simulate optical system performance. Grazing angle range on the surface of mirrors and the assembly tolerance of centre grazing incident angle were both calculated. For the working energy is 8 keV, in order to obtain sufficient reflectivity at about 1° grazing angle on each mirror, multilayer should be coated on the mirrors. Two kinds of multilayer, periodic multilayer and non-periodic multilayer (supermirror), are discussed in the paper. Take into account the grazing angle ranges on the mirrors and the grazing angle tolerance, it is necessary to have a fairly constant reflectivity over a wide angular domain. Periodic multilayer has narrow bandpass, which cannot fulfill the requirement of such wide angular domain. The non-periodic structure multilayer was designed and fabricated. The results show this kind of non-periodic multilayer can be used in K-B microscope.
