The European Space Agency is planning on launching the Atmospheric Space Interactions Monitor (ASIM) within the next three years, which will be able to better detect both dark and visible lightning from space, said ostgrd, who is part of the team that is building the ASIM gamma-ray detector.
Two concepts are central to gamma-ray detector sensitivity: detection efficiency and spectral resolution.
We also investigated placing an external gamma-ray detector just outside the dewar next to the photomultiplier tube (PMT)s to both monitor external rates and hopefully use the data from this detector to normalize the trapping data to minimize these systematic shifts in the backgrounds.
Brookhaven National Laboratory has successfully addressed this challenge with the introduction of the GammaScout, which achieves higher performance through better "as-grown" crystals and a new CZT gamma-ray detector design that can correct responses caused by crystal defects.
LJMU scientists from the Astrophysics Research Institute are at the forefront of gamma-ray research, with the robotic Liverpool Telescope on the Canary island of La Palma having a uniquely powerful capability to react rapidly to notifications from gamma-ray detector satellites -- such as NASA's Swift -- and catch the optical counterpart and fading afterglow of the explosion.
Many detector systems have common elements--an accelerator, gamma-ray detector material, computers, algorithms--so improving any of these "building blocks" might improve the capability of many detector systems, including those in the field.

To be launched in 2003, Swift will carry a gamma-ray detector, an X-ray telescope, and an optical and ultraviolet telescope.
After a decay period, the strips are placed in front of the gamma-ray detector for radiation measurement.
Fermi's Large Area Telescope is a state-of-the-art gamma-ray detector, but it's also a terrific tool for investigating the high-energy electrons in cosmic rays," said Alexander Moiseev, who presented the findings.
A germanium gamma-ray detector views the emitted photons scattered backwards from one region at a time, records their energies, and constructs a spectrum.
