A Catoptric X-Ray Optical System (For Use in Laser-Fusion Diagnostics).
Abstract
A compound x-ray imaging device has been developed as an aid in the diagnostics of a laser-fusion process which involves a pellet about 100 microns in diameter. The formation of images using x-rays is replete with geometrical aberrations among which are spherical, coma and the obliquity aberration. While techniques have been developed to minimize the spherical and obliquity aberration, coma continues to give trouble. The well known and oft quoted Abbe's sine condition deals with coma in optical systems operating at normal incidence. Its application to x-ray systems operating at grazing angles of incidence is examined in detail. The result is the development of a new sine condition which is henceforth referred to as the modified sine condition. Its successful application to a multiple mirror x-ray focusing system is demonstrated. (Author)
