Current techniques of cancer treatment using protons and heavy ions (hadrons) are an expanding branch of the external radiation therapy. Characterization of radiobiological efficiency of the hadron beams depends on the knowledge of the energy deposition distributions associated to their track structure. Novel manufacturing techniques led to the fabrication of micrometer-scale instruments for the measurement...
An ultra thin silicon detector called U3DTHIN[1,2] has been designed and built for neutral particle analyzers (NPA) and thermal neutron detection. The main purpose of this detector is to provide a state-of-the-art solution for detector system of NPAs for the ITER experimental reactor and to be used in combination with a Boron conversion layer for the detection of thermal neutrons. Currently the NPAs...
A portable system has been developed for the detection of neutrons. The sensing element is a silicon radiation detector with a Boron-based converter material that detects neutrons with the 10B(n, α)7 Li reaction. The detector response has been simulated with the MCNPX Monte-Carlo software and the detector geometry has been optimized. A portable readout electronics has been built to operate the detector...
Most neutron detectors use some type of conversion material to convert the incident neutron into secondary charged particles, which can then be detected inside the detector bulk afterward. In this way, semiconductor detectors incorporating neutron reactive material on top of a diode substrate can be used as a neutron detector. These reactions emit charged particles and recoil nucleus with energies...
