Abstract

The Solar-A Soft X-Ray telescope will be launched aboard the Japanese Solar-A Satellite in 1991, to study the sun during the next period of sunspot activity. The mechanical and optical design of this monolithic, near 2 arc-sec image quality Nariai Telescope was developed previously as explained in reference 1 and depicted in Figure 2.0. Successful achievement of the aggressive performance goals for this design required precision manufacturing and assembly, and accurate metrology to verify results. In fact, more than three-fourths of the error budget was allocated to manufacturing and meirology errors because of the recognized difficulty in producing and measuring the precision grazing-incident optical surfaces. To obtain the anufacturing precision and metrology accuracy desired, specialized tooling had to be designed to support and mount the optical substrate during the fabrication, surface metrology, alignment and assembly processes. The design considerations, the substantiating structural analyses performed and the resulting successful application of this specialized tooling are reported here in to show the difficulties often encountered in developing "support" equipment to achieve desired results in the final product.
