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

Patent number: 8461541Abstract: A radiation detector is disclosed. The detector has an entrance opening etched through a low-resistivity volume of silicon, a sensitive volume of high-resistivity silicon for converting the radiation particles into detectable charges, and a passivation layer between the low and high-resistivity silicon layers. The detector also has electrodes built in the form of vertical channels for collecting the charges generated in the sensitive volume, and read-out electronics for generating signals based on the collected charges.Type: GrantFiled: June 4, 2010Date of Patent: June 11, 2013Assignee: FinPhys OyInventors: Francisco Garcia, Risto Orava, Manuel Lozano, Giulio Pellegrini
