Energy Range
20–150 keV (scintillation counter)
Wavelength
0.1–60 Å (photometer)
The satellite X-ray ion chamber photometers covered the bands 0.1–1.6 Å, 0.5–3 Å, 1–5 Å, 1–8 Å, 8–20 Å, 6–16 Å, and 44–60 Å. It also contained a scintillation counter for the 20–150 keV region. This detector was designed to collect data on hard X-rays produced during solar flares. The UV bands covered were 170 to 500 Å, 170 to 700 Å, 1080 to 1350 Å, 1225 to 1350 Å, and 1450 to 1600 Å. Background ion chambers for the 0.5&ndasl3 Å and 1–8 Å bands, which were directed away from the Sun, were also part of the experiment complement. The ion chambers for photons of wavelength shorter than 20 Å were sampled with a time resolution of one minute. Other detectors were sampled less frequently. On 12 June 1973 the memory on Solrad 10 failed and only real-time data were aquired and processed after that time. Real-time data were then used until Solrad 11 A/B were launched in March 1976.
