Gamma ray spectroscope for determining a composition of an asteroid or the regolith of the asteroid

摘要

Disclosed and described herein are embodiments and methods of use of a gamma ray spectroscope. In one aspect the gamma ray spectroscope comprises a scintillator for receiving radiation and a solid-state photomultiplier for detecting and amplifying light emitted by the scintillator in response to the received radiation, wherein an electrical output signal is provided by the photomultiplier that is proportional to the received radiation.
