A priority of the second Ceres mission extension is collecting data with Dawn's gamma ray and neutron spectrometer
, which measures the number and energy of gamma rays and neutrons," NASA said.
Brockhouse together with its employees specializing in the field of neutron physics developed and produced a three-axis neutron spectrometer
The Fast Neutron Spectrometer
investigation will help scientists understand high-energy neutrons, part of the radiation exposure experienced by crews during spaceflight, by studying a new technique to measure electrically neutral neutron particles.
A new class of neutron detection instrumentation that offers capabilities not accessible by traditional 3He gas-filled (or other similar legacy technology) neutron systems, the Antero and Shavano Neutron Spectrometer
products feature capabilities such as location and identification of neutron radiation sources.
It is outfitted with two high-resolution cameras (including one backup), a visible and near-infrared mapping spectrometer to identify minerals on the surface, and a gamma ray and neutron spectrometer
, which will be used to reveal the presence of elements such as iron and hydrogen in the soil.
Gamma-ray and Neutron Spectrometer
(GRNS): This instrument detected gamma rays and neutrons that were emitted by radioactive elements on Mercury's surface or by surface elements that had been stimulated by cosmic rays.
Moreover, recent measurements by both the XRS and MESSENGER'S neutron spectrometer
have also shown that the highest iron abundances on Mercury are associated with a large region containing the highest magnesium, calcium, and sulfur contents on the surface, possibly the remains of an ancient impact basin.
MESSENGER's neutron spectrometer
provides a measure of average hydrogen concentrations within Mercury's radar-bright regions.
Scientists are only now analyzing the compositional results from the gamma-ray and neutron spectrometer
, since it took such a long time to build up the required signal levels during the mission's recent low-orbitalaltitude phase.
This paper discusses the capabilities and performance for this new state-of-the-art neutron spectrometer
A neutron spectrometer
aboard the Lunar Prospector detected a.
One of the instruments, known as a neutron spectrometer
, determined that thousands of square miles around the moon's north and south poles are covered with craters containing millions of tons of frozen water crystals mixed with dirt.
