First neutrons on Sharp, the CRG operated by LLB at ILL  


Following the delivery of the detector tank on November 30 2020, this week sees the first neutrons onto the cold neutron, time-of-flight spectrometer SHARP (formerly IN6 in Saclay) operated by LLB at ILL (Institut Laue Langevin, in Grenoble). The secondary spectrometer (all the elements downstream of the monochromator) has been reconstructed in a remarkable short time.

A key part of the work has been the full furbishing of the chamber with Cd coverage, installation of 240 PSD detectors along with their collimators and the associated electronics. As for the detections electronics, ILL technical teams have joined the LLB work-force for their cabling, testing and integration within the Data Acquisition System.

This new instrument coming on-line is a milestone in the improvement of neutron science for the French and European neutron scattering communities.

You will find here a short video of this new TOF spectrometer at the ILL (Amélien Genelle CEA/Irig) : Sharp-Mars-2021.mp4 (13.2 Mo)

First measurement on Sharp : deuterated Mn12 acetate at 14K. Elastic and inelastic scattering :
