Scientific paper

The Verification Engineering Test Article-I (VETA-I) was an assembly which held the largest pair of Advanced X-ray Astrophysics Facility (AXAF) mirror elements (1.2 meter diameter). The X-ray performance of this mirror pair, as held in the VETA-I, was tested in September 1991 at the Marshall Space Flight Center (MSFC) X-ray Calibration Facility (XRCF). Alignment of the optical elements to each other, and to the test facility axis, was required in order to execute the test. This paper will describe the VETA-I, its alignment requirements, and the hardware and procedures used to bring it into alignment.
