Irradiation of a Radiation Hard Charge Amplifier for Neutron Diagnostics
Abstract
Neutron diagnostic systems are essential for nuclear fusion reactors. In these systems, the detector as well as the respective analog amplifier must withstand a high neutron flux, necessitating a thorough understanding of the amplifier’s radiation tolerance and operational lifetime. In this study, CIVIDEC Cx-HiRad low-noise charge-sensitive spectroscopic amplifiers were tested. The amplifiers were exposed to 1-MeV equivalent neutron fluences ($n_{\text {eq}}$) ranging from$2\times 10^{11}$to${3\times 10^{16}}~n_{\text {eq}}$/cm2. The 1-MeV equivalent neutron flux for silicon was used, following the nonionizing energy loss (NIEL) scaling hypothesis.
