First multispacecraft ion measurements in and near the Earth’s magnetosphere with the identical Cluster ion spectrometry (CIS) experiment [PDF]

Annales Geophysicae, 2001
On board the four Cluster spacecraft, the Cluster Ion Spectrometry (CIS) experiment measures the full, three-dimensional ion distribution of the major magnetospheric ions (H+, He+, He++, and O+) from the thermal energies to about 40 keV/e.

Calibration Changes in EUV Solar Satellite Instruments [PDF]

Applied Optics, 1970
This paper reviews the problem of absolute photometric calibration in the extreme uv range with particular reference to a solar satellite instrument. EUV transfer standards, the use of predispersing spectrometers, and polarization effects at near normal incidence are discussed.
