This paper presents results from the High Efficiency Solar Panel Experiment (HESP) flown on the Combined Release and Radiation Effects Satellite (CRRES). The on-orbit solar cell degradation is correlated with the proton and electron environments. Comparisons between gallium arsenide germanium (GaAs/Ge) and silicon (Si) solar cells are presented, and results from three different annealing methods of like GaAs solar cells are compared.
A series of experiments is described in which the spectral radiant intensity of burning JP-4 is measured in the spectral region from 200 nm to 15 /mi. Spectral data are presented for small diffusion flames burning at various simulated altitudes ranging from sea level to 10.7 km. Pronounced band spectra attributable to the CO and OH radicals characterize the ultraviolet (200-310 nm) emissions which are found to increase in intensity at higher altitudes. A broadband continuum exists throughout the remainder of the spectral region examined (310 nm-15 /*m) and its intensity is seen to decrease at higher altitudes. An extremely intense CO 2 emission band at 4.4 /xm is of primary interest in this region and its possible use for fire detection is discussed.
