From SHARP to SHARPER

The original instrument SHARP (Spectromètre Hybride Alpes Région Parisienne, former IN6) was a time-focusing time-of-flight spectrometer designed for quasi-elastic and inelastic scattering. It was operated at ILL as a CRG (Collaborating Research Group) instrument with LLB (Laboratoire Léon Brillouin, Saclay, France). SHARP offered four incident wavelengths: 4.1, 4.6, 5.1 and 5.9 Å with associated energy resolutions. Recently upgraded through the SHARP+ project, it will now be operational on the full range of wavelengths from 2 to 6 Å and, at a later stage, from 6 to 12 Å, thanks to an additional Mica monochromator (currently under study). To highlight these new features, it has been decided to rename the instrument SHARPER (Spectromètre Hybride Alpes Région Parisienne Etendu en Résolution). SHARPER will remain a CRG instrument with LLB and will come online during the upcoming reactor cycle. The Instrument Responsible is Jean-Marc Zanotti. We wish SHARPER all the best for this first cycle of operation and for the future!
