Working at PN1-Lohengrin This film was shot in the RED magnet housing on 28 May 2007, i.e. between experiment 3-01-498 (Beta-gamma spectroscopy of very neutron-rich Ge, As and Se isotopes) and experim

Sorting particles with PN1 The role of a recoil spectrometer is to sort and recognize the nuclei fragments ejected from the sample very soon after fission, because the lifetime of fission products is

SANS principle Small Angle Neutron Scattering principles Neutron scattering is the process of collision between neutrons emitted by a source and a target which is the studied sample. When the scatteri

PF2 Video The film was displayed at the American Physical Society conference in March 2017.

Pedagogical animations Six animations are shown : without phase shifter (-> no contrast) normal with absorber with spin flipper, vertical analyzer (-> no contrast) with spin flipper, horizontal analyz

A simulated experiment Basics of the so called time-focussing technique Three intense neutron beams are extracted from a neutron guide by an assembly of three monochromators and are focused horizontal

Principle of the spin-echo technique Spin-echo spectrometers are based on the determination of neutron velocities by using the Larmor precession of their spin in a constant magnetic field. This is a t

IN20 and the TASSE spectrometry The movie shows the very first steps of an experiment performed on IN20 in 2008 on parahydrogen. The instrument was operated in the TASSE mode combing both neutron trip

A simulated experiment The incident polychromatic neutron beam coming from the guide H144 passes in the standard set-up a velocity selector and only a selected wavelength band continues through the gu

A simulated experiment The incoming polychromatic neutron beam (wavelength around 2.2 Å) is backscattered on the monochromator (Bragg reflexion on a crystal lattice) with a high monochromaticity (ener
