  skos:definition """The Solar Maximum Mission was a NASA satellite originally
launched on February 14, 1980. It carried the Hard X-ray Imaging
Spectrometer (HXIS, van Beek 1980), the first attempt at imaging
the sun in hard X-rays. The HXIS used a brute-force method of
imaging: an array of collimators each with a narrow field of
view, so that each collimator channel functioned as one pixel of
an imaging telescope. It achieved a spatial resolution of 8
arcsec over a 2'40'' square field of view and a 32 arcsec
resolution over a 6'24'' diameter circle. The detector used was
a position-sensitive proportional counter, consisting of two
Xe-filled chambers deep, each equipped with 450 anodes.
