AdvaPIX camera with detector coated by a thin film of LiF is able to achieve ultra-high spatial resolution for thermal neutron imaging. The camera offers sigma of Point-Spread-Function spatial resolution of up to 2.5 µm. The camera’s field of view is 14×14 mm that gives at the maximum resolution 6.5 MPix.
The camera is equipped with a Silicon sensor with a neutron conversion layer of 6LiF. Thermal neutrons are captured by 6Li that produces Alpha particles and tritons. These heavy charged particles are then detected in the Silicon sensor. The ultra-high spatial resolution is achieved by processing individual neutron hits while taking into account also charge collection in the sensor. All this advanced processing is implemented in the camera software, which is simple to use.
