First Quarter 1996

With the cryostat and optical design concepts now complete, detailed design of the cryostat commenced. A full-scale space model of the cryostat was completed. The model is being used to investigate access and techniques for assembly. A dynamic analysis of the cryostat was carried out. Further work was done to optimize the spectral resolution, spectral coverage, and slit sizes. As a result a low spectral resolution prism mode was added as an option. Potential mirror-slit fabrication methods were pursued with vendors.
