Inelastic neutron scattering is instrumental in making key discoveries in a broad range of materials, such as superconductors, multiferroic materials and quantum magnets. However, the applicability of the technique is limited by inherently weak signals, leaving parametric studies as a function of sample environment parameters relatively inaccessible.

At JCNS we develop a technical design for a future high brilliance neutron source HBS. The very compact design of the neutron source allows to extract larger phase space volumes from the neutron moderators as compared to existing facilities, where the minimum distance between the moderator and extraction system and/or first choppers poses a significant constraint.
In this presentation we...
The first Neutron Spin Echo (NSE) instrument, IN11, was in user operation for 40 years. The newest spin echo instrument WASP took the relay and just had its first full year of user operation. I will use this occasion to review how the design of the wide angle NSE spectrometers has developed over the years.
Apart from WASP, all non-resonant Neutron Spin Echo spectrometers use the basic IN11A...
The Marmot project is a new type of multiplexed secondary spectrometer for cold triple axis instruments.
It is based on a novel concept of energy analysis, using a large array of bent silicon blades and a position sensitive detector. By its particular geometry, it allows for continuous analysis of the neutron energy in a wide energy range (about 3.5 to 7 meV) and with a large divergence....
Polarisation analysis (PA) has been growing in popularity to separate the coherent and incoherent scattering contributions in complex systems. For quasielastic spectroscopy, PA has been used with neutron spin-echo, triple axis, and direct geometry time of flight spectrometers. However, crystal analyser backscattering instruments are the workhorses of quasielastic neutron scattering (QENS), due...
