... The Chandra Ground Calibration Raytrace Database and Simulator provides simulations of tests performed on the Chandra X-Ray Observatory's High Resolution Mirror Assembly (HRMA). ... Prior to its July 23, 1999 launch, the Chandra X-Ray Observatory's High Resolution Mirror Assembly (HRMA) underwent extensive ground calibration (Weisskopf & O'Dell 1997) at Marshall Space Flight Center's X-Ray Calibration Facility (XRCF). ... When determining subsystem parameters the XRCF raytrace simulator, . ...
... The then president of the Society, Mr. Robert Burke, appointed a committee of eight or ten members, most of whom had made smaller mirrors, as an instrument committee, with Mr. Thorpe as chairman. ... Seriously, the best practicable solution seemed to be to build a machine to do the grinding and polishing. ... It was decided to grind the edges of the mirror to make it truly circular, as the rough cast glass was some 3/8 inch longer on one diameter than on the other. ...

... Holes in the plug plates for the Sloan Digital Sky Survey must be positioned and sized accurately. We tested several techniques by drilling holes in a number of test plates and measuring the characteristics of each hole. ... Four different kinds of drill bit were used, two plates per type of bit, for a total of eight test plates. ... Plate 1: Speed Test . ... Based on the drilling tests, we can hold hole diameter error to 15 ?m RMS (likely better if we can get bit-to-bit variation down). ...
