Recently, we employed the Larmor-diffraction technique (at neutron source FRMII, instrument TRISP of Max-Planck Institute for Solid State Research) for high-precision measurements of lattice constants under high pressure. We also attempt to use elliptic neutron guides (figure), which focus broad neutron beams on the tiny sample space available in high-pressure cells.
