Scientific paper

A process for precision diamond mirror turning, mechanical polishing, lacquer coating, and metal deposition is described which produces X-ray telescopes with arcminute angular resolution at moderate cost. Calibration results for an 80-cm (31.4-in.) diameter Wolter I telescope flown aboard an Aries sounding rocket are presented. It is suggested that surface waveness on scales above 20 mm might explain the X-ray halos and efficiency loss noted. The mirrors, however, had sufficient collecting area and angular resolution to be of use in obtaining X-rays observations for realistic experiments.
