Thermal neutrons have widespread applications ranging from fundamental physics tests to neutron tomography, solid-state physics and medical physics, making their detection important. Thermal neutrons are traditionally detected with Helium-3 filled proportional counters. However, due to the supply shortage of Helium-3, leading to a rapid increase in its price, alternative detectors are sought.
In Bonn, the BOron DEtector with Light and Ionization Reconstruction (BODELAIRE) is being developed with the aim of providing high spatial and time resolution in thermal neutron detection. The BODELAIRE is based on the principle of a Time Projection Chamber (TPC) with thin layers of Boron-10 neutron converters placed perpendicular to a GridPix readout which will have Timepix3 as ASIC. The trigger is placed along the field cage and consists of multiple layers: Boron, scintillator and light readout. Thus, the working principle is that the conversion of the neutron with Boron-10 gives two tracks, one giving a trigger signal in the scintillator while the other leaves a track in the gas volume.
The concept and current development status of the BODELAIRE will be presented.
