In-situ calibration of the efficiency of a yttrium activation detection system by the accelerator-based DD fusion neutron source
Fig. 1. Pulse height spectra measured when the detector is close to the target (orange) and away from the target (blue)
Fig. 3. Time-PSD distribution of the events measured under different conditions
Fig. 4. Count rates of the events measured when no yttrium disk is installed
Fig. 5. Using the yttrium disks with two different thickness, the neutron fluxes are reconstructed from the measurements
Fig. 6. Simulated of the radioactivation of the yttrium disk varieds with time
Fig. 7. Simulation of the radioactivation of the yttrium disk for different time bin width
Fig. 8. Count rates of the events of which the QDC values are between
