Abstract:

Theories of x-ray diffraction applicable to x-ray astronomy techniques are developed. The preparation of crystals for maximum diffracted intensity is discussed and experimental measurements for LiF and graphite are given. The role of the integrated reflection coefficient in maximizing and calculating the effective gain of astronomical instruments is discussed. Two instruments, The Confocal Paraboloid X-ray Lens and The Asymmetric Bragg Cosmic X-ray Polarimeter are presented as examples and their performance estimated. A flight model of the Lens and a laboratory model of the Polarimeter have been constructed details are given.
