Nuclear Compton Telescope


The Nuclear Compton Telescope is a balloon-borne Compton telescope to observe the gamma-ray sky in the energy range from a few hundred keV to several MeV. Its main goals are to improve the understanding of Galactic nucleosynthesis, gamma-ray bursts, supernovae, black holes, and more.

Instrumentation

The Compton telescope uses an array of twelve Germanium detectors with high spectral resolution to detect gamma rays. On its bottom half the detector is surrounded by a Bismuth germanate scintillator to shield it from atmospheric gamma rays. The telescope has an overall field of view of 25% of the sky.

Flights

Since low-to-medium-energy gamma rays are only detectable from above the atmosphere, NCT is launched with a large Helium balloon into the stratosphere. So far NCT had two successful and one unsuccessful balloon campaigns:
