Patent number: 9395454Abstract: A device for detecting neutrons includes at least one common module, where a number of solid state sensors are assembled. The sensors are configured in the module side by side and/or stacked in a layered structure. At least one of the sensors includes neutron reactive material as a neutron converter for interacting with neutrons incident thereon to be detected and to release ionizing radiation reaction products responsive to interactions with the incident neutrons. The neutron converters are coupled with corresponding semiconductor elements so that the semiconductor elements interact with the ionizing radiation reaction products for providing electrical charges in proportion to the energy of the ionizing radiation reaction products. The semiconductor elements are configured with electrodes for providing charge collection areas for collecting the electrical charges and to provide electrically readable signals proportional to the collected electrical charges.Type: GrantFiled: October 25, 2013Date of Patent: July 19, 2016Assignee: FINPHYS OYInventors: Risto Orava, Tom Schulman, Petteri Mehtala
