Abstract

The hard x-ray imaging spectrometer (HXIS) is one of the instruments aboard the NASA Solar Maximum Mission satellite. For the imaging of solar flares in hard x rays HXIS employs a grid collimator with an 8-sec of arc FWHM angular resolution. The collimator consists of ten grid plates in a sequence. The position accuracy of the grids in their planes must be better than a few microns. This paper describes a simple optical alignment method developed to perform measurements of the grid positions with a precision of 1 μm.
