AbstraktAbstract

The imaging semiconductor pixel detector Timepix allows the charge collected in each of its 256x256 pixels (55 μm pitch) to be measured. This feature makes it suitable for applications where the energy and position of incoming radiation needs to be determined We are developing a fast neutron spectroscopy and radiography technique that is based on tracking protons recoiled by fast neutrons. The proposed setup consists of a hydrogen rich converter placed above the Timepix detector surface, which is irradiated by fast neutrons. The protons recoiled by neutrons interacting in the converter hit the detector and generate a track. Analysis of the tracks give the energies, positions and directions of flight of the protons. This information was used to reconstruct energy of the incoming neutrons. The neutron source position can be calculated as well.
