Each sensor operates in an identical manner wherein a neutron can be absorbed by 3He atoms in the gas volume producing a proton and a triton with a total energy of 765 keV. The proton and triton deposit their kinetic energy in the gas volume, producing a signal corresponding to 764 keV that serves as an unambiguous indicator of a detected neutron. The data from each sensor has the same format and consists of 256 channels that are accumulated during each accumulation period. urn:nasa:pds:context:instrument:psyche.ns is_instrument Solar System Planetary System urn:nasa:pds:context:target:planetary_system.solar_system bundle_to_target urn:nasa:pds:context:resource:resource.psyche.ns_online has_resource Archive urn:nasa:pds:psyche.ns:document::3.0 Primary bundle_has_document_collection urn:nasa:pds:psyche.ns:data_raw::3.0 Primary bundle_has_data_collection
