Développement d'une cellule champ électrique thermalisé pour la diffusion neutronique aux petits angles

Abstract : A cell was developed at the Léon Brillouin Laboratory (LLB) allowing one to apply an electric field to a heated sample during a Small Angle Neutron Scattering (SANS) experiment. To avoid decomposition of the sample by electrolysis, the electrodes have to be isolated. As part of a European instrumentation program (Joint Research Activities (JRA) 2012-2016), a prototype was produced by 3D-printing at the Léon Brillouin Laboratory (LLB). The electrodes are placed outside the sample cuvette and the prototype has been designed to receive a stream of heated air allowing thermalization of the sample. This prototype was manufactured after Finite Element Methods simulations (COMSOL® Multiphysics) to improve the electric field range. Tests of electric field and thermalization have been carried out.
