Benjamin Koch TU Wien, Austria The discrepancy between the measured lifetimes of free neutrons using beam and bottle experiments has persisted for over two decades and remains unresolved. In this talk, I

clamps are capable of 20-30 kbar (2-3 Gpa) but at the expense a very narrow angular opening for the beam window, and this was really not sufficient for some types of research. A solution would be a design

gap between the coils compatible with the size of the neutron beam; asymmetric coil blocks to shift the zero field out of the neutron beam. They had to come up with a specific design - the "asymmetric ... good-sized samples. At the same time, it needed a non-zero field around the gap to keep the neutron beam polarised as it crosses the cryomagnet; ...

of atoms. The neutron has no electric charge but has a spin and a magnetic moment. Neutron beams - like beams of X-rays, electrons or muons - are valuable tools for studying the multitude of materials

of a monochromatic beam by a single crystal This demonstrates the influence of the wavelength of the incoming beam on the diffraction process. Diffraction of a monochromatic beam by a crystallin powder ... of which it demonstrates the following aspects: Laue diffraction (diffraction of a polychromatic beam by a single crystal) You can appreciate ...

from LANSCE which allows you to calculate the activation of a sample after it has been in a neutron beam for one day and the amount of time for it to decay to 2nCi/g or less.
