Neutron imaging is a method to research materials non-invasively. In the University of Bonn, we are developing a state-of-art neutron imaging detector with a high spatial resolution.
As a neutron converter, we use a B(10) and Gd enriched Microchannel plate detector (MCP). The MCP has been studied with cold and thermal neutrons for neutron imaging and it already showed very promising results in means of neutron detection efficiency and spatial resolution. Our aim is to design a novel detector which will combine the efficiency of the MCP with a good time and spatial resolution readout system.
The detector readout is achieved by 4 Timepix3 AISCs. The Timepix3 is an upgraded version of Timepix with additional features of package based readout and better timing resolution of upto 1.5 ns. With the help of the new readout technique, it has less counting losses. It can simultaneously record arrival time and time over threshold. A Timepix3 can achieve good timing resolution and spatial resolution at the same time.
In this talk, we will present the concept and the current status of the first prototype of the neutron sensitive MCP on a Timepix3 readout.
