High Resolution γ-Ray Spectroscopy: the First 85 Years

This opening review attempts to follow the main trends in crystal diffraction spectrometry of nuclear γ rays from its 1914 beginning in Rutherford's laboratory to the ultra-high resolution instrumentation realized in the current generation of spectrometers at the Institute Laue Langeven (ILL). My perspective is that of an instrumentalist hoping to convey a sense of our intellectual debt to a nu...

Prototype high resolution multienergy soft x-ray array for NSTX.

A novel diagnostic design seeks to enhance the capability of multienergy soft x-ray (SXR) detection by using an image intensifier to amplify the signals from a larger set of filtered x-ray profiles. The increased number of profiles and simplified detection system provides a compact diagnostic device for measuring T(e) in addition to contributions from density and impurities. A single-energy pro...

“Neutron Shell”: A high efficiency array of neutron detectors for γ−ray spectroscopic studies with Gammasphere

A shell of neutron detectors was designed, constructed, and employed in γ−ray spectroscopy with Gammasphere. It consists of up to 35 tapered regular hexagons that replace the same number of forward Ge-detector modules in Gammasphere. The shell was designed for high detection efficiency and very good neutron−γ discrimination. The simultaneous use of time of flight, and two methods of pulse shape...

Very High Energy γ − ray Emission from Crab Nebula with the PACT Array

The Crab nebula has proved to be the nearest to a standard candle in VHE γ− ray astronomy. Results on the gamma ray emission from the nebula at various energies have come in the last decade mostly from imaging telescopes. The aim of the new Pachmarhi Atmospheric Cerenkov Telescope (PACT) array has been to use the temporal and spatial distribution of Cerenkov photons in distinguishing between pr...
