The new thermal time of flight spectrometer at NFL

At the Neutron Forsknings Laboratoriet in Studsvik, the Swedish center for neutron scattering, a new thermal time of flight spectrometer has recently been completed, and the instrument is now open for beam-time applications, from both Swedish and international users. The construction uses a monochromatic beam of 2.48-A neutrons which is pulsed by a Fermi chopper. The scattered neutrons are detected by an array of 3He detectors. The resolution (full width at half maximum) is 0.6 meV and the flux at the sample position is 5×103 neutrons cm-2 s-1. The instrument is presently best suited for quasi-elastic neutron-scattering experiments.
