The Silicon Carbide (SiC) Solid State Detector (SSD) is an interesting alternative to diamond detector for fast neutron detection and spectroscopy. Despite this, and unlike diamonds, SiC was never installed on a Tokamak and, thus, was never characterized on a fusion plasma emission. This work aims to predict the response of a SiC when exposed to the neutron spectrum of future Tokamak devices. This is achieved by combining the neutron spectra measured by diamonds during the DTE2 JET campaign with the experimental characterization of SiC at various neutron energies on spallation and DT sources performed in the past through the means of a Geant4 simulation. The SiC response to an ideal thermal plasma and to a neutron and gamma mixed fields are also produced.

Abstract
The Silicon Carbide (SiC) Solid State Detector (SSD) is an interesting alternative to diamond detector for fast neutron detection and spectroscopy. Despite this, and unlike diamonds, SiC was never installed on a Tokamak and, thus, was never characterized on a fusion plasma emission. This work aims to predict the response of a SiC when exposed to the neutron spectrum of future Tokamak devices. This is achieved by combining the neutron spectra measured by diamonds during the DTE2 JET campaign with the experimental characterization of SiC at various neutron energies on spallation and DT sources performed in the past through the means of a Geant4 simulation. The SiC response to an ideal thermal plasma and to a neutron and gamma mixed fields are also produced.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
