THE GAMMA RAY EXPERIMENT for the SMALL ASTRONOMY SATELLITE B (SAS-B) C. E. Fichtel, C. H..~Hrmann, R. C. Hartman, D. A. Kniffen
THE GAMMA RAY EXPERIMENT FOR THE SMALL ASTRONOMY SATELLITE B (SAS-B) C. E. Fichtel, C. H.. ~hrmann, R. C. Hartman, D. A. Kniffen, H. B. Ogelman*, and R. W. Ross Goddard Space Flight Center, Greenbelt, Md. 20771 Abstract A magnetic core digitized spark chamber gamma ray telescope has been developed for satellite use and will be flown on SAS-B in less than one year. The SAS-B detector will have the following characteristics: Effective area ~ 500 cm2 , solid angle = ~ SR; Efficiency (high energy) ~ 0.29; and time resolution of better than two milliseconds. A detailed picture of the galactic plane in gamma rays should be obtained with this experiment, and a study of point sources, including short bursts of gamma rays from supernovae explosions, will also be possible. 1. Introduction The SAS-B gamma ray telescope represents the first satellite version of a planned evolution of a gamma ray digitized spark chamber telescope which began with the development of a balloon borne instrument. The telescope is aimed at the study of gamma rays whose energy exceeds about 20 MeV. In the early 1960's, it was realized that the celestial gamma ray intensity was very low compared to the high background of cosmic ray particles and earth albedo. For this reason, a picture type detector seemed to be needed to identify unambiguously the electron pair produced by the gamma ray and to study its properties - particularly to obtain a measure of the energy and arrival direction of the gamma ray. In addition, the secondary gamma ray flux produced by cosmic rays in the atmosphere, even at the altitudes of the present large balloons, severely limits the gamma ray astronomy which can be accomplished with balloons and dictates that gamma ray ~stronomy must ultimately be accomplished with detector systems on satellites. -

The ongoing all-sky X-ray survey of the SRG space observatory with data acquired by the ART-XC and eROSITA telescopes can provide a possibility to fully explore the resonant production mechanism of the dark matter sterile neutrino, which exploits the lepton asymmetry in the primordial plasma consistent with cosmological limits from the Big Bang Nucleosynthesis. In particular, it is shown that at the end of the four year all-sky survey, the sensitivity of the eROSITA telescope near the 3.5 keV line signal reported earlier can be comparable to that of the XMM -Newton with all collected data, which will allow one to carry out another independent study of the possible sterile neutrino decay signal in this area. In the energy range below ≈ 2:4 keV, the expected constraints on the model parameters can be significantly stronger than those obtained with XMM -Newton. -

NASA's Great Observatories
NASA’s Great Observatories To grasp the wonders of the cosmos, and understand its infinite variety and splendor, we must collect and analyze radiation emitted by phenomena throughout the entire electromagnetic (EM) spectrum. Towards that end, NASA proposed the concept of Great Observatories, a series of four space-borne observatories designed to conduct astronomical studies over many different wavelengths (visible, gamma rays, X-rays, and infrared). An important aspect of the Great Observatory program was to overlap the operations phases of the missions to enable astronomers to make contemporaneous observations of an object at different spectral wavelengths. The first element of the program -- and arguably the best known -- is the Hubble Space Telescope (HST). The Hubble telescope was deployed by a NASA Space Shuttle in 1990. A subsequent Shuttle mission in 1993 serviced HST and recovered its full capability. A second successful servicing mission took place in 1997. Subsequent servicing missions have added additional capabilities to HST, which observes the Universe at ultraviolet, visual, and near-infrared wavelengths. Diagram of the Space Telescope, 1981 Since its preliminary inception, HST was designed to be a different type of mission for NASA -- a long term space- based observatory. From its position 380 miles above Earth's surface, the Hubble Space Telescope has contributed enormously to astronomy. It has expanded our understanding of star birth, star death, and galaxy evolution, and has helped move black holes from scientific theory to fact. Credited with thousands of images and the subject of thousands of research papers, the space telescope is helping astronomers answer a wide range of intriguing questions about the origin and evolution of the universe. -

Permission is not requested for duplication. EP-1998-12-384-HQ NASA’s Great Observatories Why are space observatories important? The answer concerns twinkling stars in the night sky. To reach telescopes on Earth, light from distant objects has to penetrate Earth’s atmosphere. Although the sky may look clear, the gases that make up our atmosphere cause problems for astronomers. These gases absorb the majority of radiation emanating from celestial bodies so that it never reaches the astronomer’s telescope. Radiation that does make it to the surface is distorted by pockets of warm and cool air, causing the twinkling effect. In spite of advanced computer enhancement, the images finally seen by astronomers are incomplete. Observatories located in space collect data free from the distor- tion of Earth’s atmosphere. Space observatories contain advanced, highly sensitive instruments, such as telescopes (the Hubble Space Telescope and the Chandra X-ray Observatory) and detectors (the Compton Gamma Ray Observatory and Chandra X-ray Observatory), that allow scientists to study radia- tion from neighboring planets and galaxies billions of light years away. -

There are occasions when science objectives require high time-resolution measurements, and the instrument operates in short measurement cycles, sampling only a portion of the velocity distribution function. One such high-resolution measurement strategy consists of sampling the two-dimensional pitch-angle distributions of the plasma particles, which describes the velocities of the particles with respect to the local magnetic field direction. Here, we investigate the accuracy of plasma bulk parameters from such high-resolution measurements. We simulate electron observations from the Solar Wind Analyser’s (SWA) Electron Analyser System (EAS) on board Solar Orbiter. We show that fitting analysis of the synthetic datasets determines the plasma temperature and kappa index of the distribution within 10% of their actual values, even at large heliocentric distances where the expected solar wind flux is very low. -
