A model of one of the earliest spectrometers (neutron scattering?) used on NRX. It is believed it would have been mounted against the NRX thermal column but despite significant effort, no details have been uncovered as to what experiments it was used for nor who its researchers/designers might have been. A beam of neutrons would have entered the spectrometer at the right hitting a sample which it appears could be rotated at various angles, or even spun. This would indicate it was used for neutron scattering as opposed to nuclear physics measurements. There has been no confirmation that it was actually built. The model stands about 30 cm tall.
