Spectral dependence of the quantum efficiency η0(E) of our detector. Circles: calibrated data; line: our analytical approximation of these data. The detector includes an 8.5 µm-thick NE102 plastic scintillator, an optical bundle of diameter 6 mm, and a H3165-10 photomultiplier (Hamamatsu Photonics) operated at 1 kV. |
