HXRBS
The Hard X-Ray Burst Spectrometer (HXRBS) was designed to examine the role of energetic electrons in solar flares by measuring the variations in intensity and energy of the hard X-ray fluxes. Scintillation events in its actively collimated CsI(Na) detector were read out every 128 ms in fifteen energy channels between ~25 to ~500 keV. A circulating memory was able to accumulate relatively brief periods of data during the more intense flares with time resolution down to 1 ms. The full width at half maximum of the field of view was approximately 40 degrees. Additional information available at "http://umbra.nascom.nasa.gov/smm/hxrbs.html" [Summary provided by NASA]
