Fabricating Sub-collimating Grids for an X-ray Solar Imaging Spectrometer using LIGA Techniques
This paper describes fabrication of sub-collimating X-ray grids that are used in an instrument for the High Energy Solar Spectroscopic Imager ( HESSI ), a proposed NASA mission that will promote understanding of solar particle acceleration and explosive energy release in the magnetized plasmas at the Sun. The HESSI comprises 12 rotating pairs of high-aspect-ratio, high-Z grids; each pair is separated by 1.7 meters and backed by a single Ge detector.

Fine Pitch Grids for an X-Ray Solar Imaging Spectrometer Fabricated by Optical Lithography and XeF2 Etching
Fine-pitch, sub-collimating X-ray grids have been developed for an instrument in the High Energy Solar Spectroscopic Imager , a proposed NASA mission. In addition to high-energy x- rays, the instrument requires collimation of photons with energies of less than 4 keV such that free-standing grids are required that have no material between the grid slats. Fabrication of these grids is described.
