This PSB Spotlight will comprise of half a day of lectures (in the IBS seminar room) on the different neutron techniques available at the Institut Laue-Langevin which are useful for biology. Lectures will cover small-angle scattering (SANS), reflectometry, crystallography, inelastic scattering, and deuteration. A special focus will be on the complementary information that neutrons provide with respect to other techniques, including X-rays, Cryo-EM and NMR, as well as on the practical requirements on the sample state for the different neutron techniques.
