(a) Response calibration of the UNCD I detector, W = 13.27 eV ± 0.12 eV. The inset is the I–V curve of the UNCD I detector and the arrow indicates the operating bias for the response calibration. (b) Response calibration of the UNCD III detector, W = 13.16 eV ± 0.15 eV, with obvious deviation from linearity as flux becomes high. |
