研制了两台电子能谱仪，用于表征MeV范围内的电子闪烁计数器。这些光谱仪提供0.4至1.8 MeV的单能电子束，在1 MeV时的能量分辨率(FWHM)为1.0±0.2%，线性度优于2%。光束的横向轮廓由典型的3.0 mm高斯宽度组成。这些电子束可以以1毫米的增量自动扫描高达60×200平方厘米的表面。他们已经被用于超NEMO实验的量热计模块的开发。
Two electron spectrometers have been developed for the characterisation of scintillating counters with MeV range electrons. These spectrometers offer a monoenergetic electron beam ranging from 0.4 to 1.8 MeV with an energy resolution (FWHM) of 1.0 ± 0.2% at 1 MeV and a linearity better than 2%. The transverse profile of the beams consists of a typical 3.0 mm Gaussian width. These electron beams can automatically scan surfaces up to 60 × 200 cm2 in 1 mm increments. They have been used in the calorimeter module development for the SuperNEMO experiment.
