High resolution neutron Larmor diffraction using superconducting magnetic Wollaston prisms

Abstract The neutron Larmor diffraction technique has been implemented using superconducting magnetic Wollaston prisms in both single-arm and double-arm configurations. Successful measurements of the coefficient of thermal expansion of a single-crystal copper sample demonstrates that the method work...
