Figure 6.

The $1/\lambda$ for pCVD diamond in the fast neutron irradiation. The two values shown at each fluence are the values for positive (solid markers) and negative (open markers) bias at $E= \pm 2 \mathrm{V}/\mathsf{\mu }\mathrm{m}$. The data were fit with a first-order damage curve independently for each sample.
