Abstract: A neutron detector system, with a detector having a pair of spaced diamond detector layers, sandwiched between outer silicon layers. In response to incident neutrons, the detector system measures pulse heights and response times, and from those measurements, calculates the carbon recoil energy and time of flight of scattered neutrons. This data is further used to calculate a “direction cone”, which represents the approximate angle of arrival of the incident neutron. These direction cones can be used to image neutron events.

Abstract: A relatively compact dual ion composition instrument and associated methodology for measuring plasma and ion populations in a variety of interplanetary and planetary environments. The unitary device can measure mass and ionic charge state compositions and 3D velocity distributions of 10 eV/q to 40 keV/q plasma and pick-up ions; and (2) mass composition, energy spectra and angular distributions of 30 keV to 10 MeV energetic ions.

Abstract: The present invention aims at providing a method and apparatus for monitoring operation of a thermal device, which allows accurate understanding of the operating states up until occurrence of a failure. The method includes the steps of: storing in sequence detection data on operating states and detection time thereof as operating state data at specified time intervals; storing detection data and detection time in the event of a failure in a thermal device as point-of-failure data; storing operating state data for a specified period of time including failure occurrence time; and outputting the same. The apparatus is equipped with detection means for detecting operating states, processing means, storage means and output means.
