Low-Frequency Measurements of the Cosmic Background Radiation Spectrum

Description: The long-wavelength spectrum of the cosmic background radiation has been measured at five wavelengths (0.33, 0.9, 3.0, 6.3, and 12.0 cm). These measurements represent a continuation of the work reported by Smoot et al. (1983). The combine results have a weighted average of 2.73 {+-} 0.05 K and are consistent with past measurements. They limit the possible Compton distortion of the Cosmic Background Radiation spectrum to less than 8%.

Total Absorption Shower Counter Test

Description: We propose to conduct a short test to check the basic concepts used in the Total Absorption Shower Counter (TASC) being developed for the Alvarez cosmic-ray experiment (BCR-5) on the HEAO-B satellite. The objective is to ascertain whether the probability for an incoming proton of energy E {ge} 100 GeV to interact in the TASC and simulate the response due to an incoming e{sup {+-}} is smaller than 10{sup -4}. We will thereby obtain a preliminary estimate of whether the TASC should be able to dis… more

RADIOMETER SYSTEM TO MAP THE COSMIC BACKGROUND RADIATION

Description: We have developed a 33 GHz airborne radiometer system to map large-scale angular variations in the temperature of the 3 K cosmic background radiation. A ferrite circulator switches a room-temperature mixer between two antennas pointing 60{sup o} apart in the sky. In forty minutes of observing, the radiometer can measure the anisotropy of the microwave background with an accuracy of {+-} 1 m{sup o}K rms, or about one part in 3000 of 3 K. The apparatus is flown in a U-2 jet to 20 km altitude wher… more
