Abstract : The report describes the recalibration of a magnetic spectrometer designed to measure the 0.1- to 1.0-MeV electron flux in a space environment. A different technique from that of the original calibration was used. In the present case, a Monte Carlo computer program and beta source measurements are used to determine the detected energies and their detection efficiencies. The mean energies were 20 to 40 keV higher and the normalizations were a factor of two higher than those previously found. Systematic errors effects and the degree of elastic scattering off the magnet faces are analyzed. (Author)
