Materials Activation Study on the EAST Neutral Beam Injection Port dataset

The neutron source at the NBI sample, the activation characteristics and the dose rate after shutdown are displayed and analyzed. Figure 1 shows the two-dimensional model of EAST NBI, and Figure 2-3 shows the operating parameters of EAST NBI.

Table 1 shows the composition ratio of window material samples. Based on these parameters and models, Fig. 4 - Fig. 5 shows the neutronics characteristics of the sample. Figure 6 - Figure 8 shows the gamma spectrum, material radioactivity and shutdown dose rate of the sample material after activation.
