The Transient Gamma-Ray Spectrometer (TGRS) to be flown aboard the WIND spacecraft is primarily designed to perform high resolution spectroscopy of transient γ-ray events, such as cosmic γ-ray bursts and solar flares over the energy range 25 keV to 8.2 MeV with an expected spectroscopic resolution of ∼ 3 keV at 1 MeV. The detector itself consists of a 215 cm3 high purityn-type Ge crystal kept at cryogenic temperatures by a passive radiative cooler. The geometric field of view defined by the… 
Transient Gamma-Ray Spectrometer Observations of Gamma-Ray Lines from Novae. III. The 478 keV Line from 7Be Decay
The Wind spacecraft, which carries the Transient Gamma Ray Spectrometer (TGRS), moves in an extremely elliptical orbit that largely avoids Earth's trapped radiation belts and albedo γ-radiation. The
Status of instrumental background simulations for gamma-ray telescopes with Geant4
Hard X-ray and low-to-medium-energy gamma-ray telescopes may be exposed to many different types of background radiation ranging from cosmic rays to secondary particles from Earth’s atmosphere and
Germanium (Compton) focal plane detectors for gamma-ray lenses
With focusing of gamma rays in the nuclear-line energy regime establishing itself as a feasible and very promising approach for high-sensitivity gamma-ray studies of individual sources, optimizing
Monte Carlo study of detector concepts for the MAX Laue lens gamma-ray telescope
MAX is a proposed Laue lens gamma-ray telescope taking advantage of Bragg diffraction in crystals to concentrate incident photons onto a distant detector. The Laue lens and the detector are carried
Imaging with the test setup for the coded-mask INTEGRAL spectrometer SPI : performance of a coded aperture γ-ray telescope at 60 keV - 8MeV
The European Space Agency's INTErnational Gamma-Ray Astrophysics Laboratory (INTEGRAL) was launched on October 17, 2002. It carries two gamma-ray telescopes, the imager IBIS and the spectrometer SPI,
The Modelling of Background Noise in Astronomical Gamma Ray Telescopes
Gamma ray photons interact with matter through a wide variety of complex physical mechanisms, which can be readily imitated by other particle processes. Unfortunately since γ-ray telescopes are


The Transient Gamma-Ray Spectrometer
The authors describe the Transient Gamma-Ray Spectrometer (TGRS) to be flown onboard the WIND spacecraft. This instrument is designed to detect cosmic gamma -ray bursts over the energy range of 20
The directivity of high-energy emission from solar flares - Solar Maximum Mission observations
The data base consisting of flares detected by the gamma-ray spectrometer (GRS) on board the Solar Maximum Mission (SMM) satellite is used to study the directivity of high-energy radiation. A number
Evidence for cyclotron absorption from spectral features in gamma-ray bursts seen with Ginga
Absorption features near 40 keV in the spectra of several gamma-ray burst sources, first reported by Mazets et al., have been widely ascribed to cyclotron absorption, implying that a strongly
Gamma-ray spectroscopy of the galactic center region - Confirmation of the time variability of the positron annihilation line
The GSFC Low-Energy Gamma-Ray Spectrometer observed the region of the galactic center during a balloon flight from Alice Springs, Australia, on 1981 November 20. No significant excess over background
Spatial distribution of γ-ray bursts observed by BATSE
THE nature of the sources of cosmic γ-ray bursts is a long-standing problem in astrophysics. Lack of knowledge of their true spatial distribution and of their intrinsic brightness has hampered
The nature of the annihilation radiation and gamma-ray continuum from the Galactic center region
Analysis of the observations of the time-dependent, electron-positron annihilation line radiation and gamma-ray continuum emission from the region of the Galactic center shows that ther are two
High-resolution spectroscopy of two gamma-ray bursts in 1978 November
The first results from the ISEE3 radiatively cooled germanium gamma-ray burst spectrometer are presented. Spectra and time histories from two events on 1978 November 4 and 19 are given. A significant
Cosmic Gamma‐Ray Bursts
The experimental aspects of gamma-ray bursts are reviewed, including their time histories, energy spectra, spatial distribution, recurrence rate, and number-intensity relation. Although the
