Mission Name: SMS 2The X-ray counter was composed of a collimator, two ionization chambers, and two electrometers. A small angular aperture was chosen for the telescope collimator. The collimator, mounted so its axis declination was controlled by ground command, viewed the full disk of the sun once every vehicle rotation. One ion chamber, filled with argon at 1 atm, detected 1- to 8-A X rays, and had a 1.27E-4 m beryllium window to exclude X rays of longer wavelengths. The other chamber was filled with xenon at 1.5 to 2 atm and had a 1.27E-3 m beryllium window to measure X rays of 0.5 to 3 A.
