Abstract
A neutron conversion foil for being used in a neutron detector includes a substrate having a first and second side. The substrate is covered at least on one of the first and second sides with a neutron conversion layer made of a neutron reactive material and being capable of capturing neutrons to thereafter emit light and/or charged particles. The neutron conversion foil is transparent to light such that light originating from the conversion of neutrons can pass through one or several of the neutron conversion foils and thereafter be collected and detected by a light sensing device.

A neutron conversion foil for being used in a neutron detector, said neutron conversion foil being configured to be arranged in a scintillator volume and comprising a substrate having a first side and a second side,
- whereby said substrate is covered at least on one of said first side and said second side with a neutron conversion layer made of a neutron reactive material and being capable of capturing neutrons to thereafter emit light and/or charged particles to be detected by a light sensing device, and
- whereby said neutron conversion layer and substrate are transparent to light originating from conversion of the neutrons, and are configured to be arranged such that the light originating from the conversion of the neutrons can pass through and away from the substrates and neutron conversion layers of one or several of said neutron conversion foils and thereafter be collected and detected by the light sensing device.
A neutron detecting device comprising:
- a scintillation volume filled with a scintillating material such as a noble gas;
- at least one light sensing device in optical contact with the scintillating volume;
- one or more neutron conversion foils, the neutron conversion foils each comprising a substrate having a first side and a second side, whereby said substrate is covered at least on one of said first side or said second side with a neutron conversion layer made of a neutron reactive material and being capable of capturing neutrons to thereafter emit light and/or charged particles to be detected by the at least one light sensing device, and whereby said neutron conversion layer and substrate are transparent to light originating from conversion of the neutrons, and are configured to be arranged such that the light originating from the conversion of the neutrons can pass through and away from the substrate and neutron conversion layers of one or several of said neutron conversion foils and thereafter be collected and detected by the at least one light sensing device,
- wherein said one or more neutron conversion foils are positioned in said scintillation volume and in optical contact with said scintillating material, and are configured to be arranged such that charged conversion products arising from neutron capture in said one or more neutron conversion foils escape into said scintillation volume and produce light, to which said one or more neutron conversion foils is transparent, and wherein the produced light is detected by the light sensing device.
