Bonner sphere spectrometer for neutron spectra
Bonner sphere spectrometer with ³He proportional counters for thermal neutrons, each housed in a spherical HDPE moderator of a different diameter. It comes with a single detector moved between the spheres or with up to 16 detectors measuring at the same time, and the RUFUS software unfolds the neutron spectrum.
