BRISP - TOF Spectrometer for Small Angle Inelastic Scattering

BRISP is a new concept thermal neutron Brillouin scattering spectrometer which exploits the time-of-flight technique and is optimized to operate at small scattering angles with good energy resolution.

The detector

The position sensitive neutron detector (PSD) is a set of 3He tubes. The assembly can be moved inside the detector tank to adjust the instrument resolution.

When the photo was taken, not all the tubes were already installed.
