Scientific paper

The electronics for a balloon-borne polarimeter operating in the 100 to 2000 micron wavelength range with a spurious polarization less than 0.1%, which has been successfully employed in the balloon flight in July 1971, is described. Measurements of the polarized infrared radiation from celestial bodies, in the 100 to 2000 micron range, are presented. The control circuitry is discussed, including topics such as pointing control of the optical bench, black body for in-flight bolometer calibration and temperature measurement, chopper velocity, check of the power supplies, and opening of the door. The PCM telemetry system is outlined.
