At the FRM II a UCN source with a solid deuterium converter and solid hydrogen premoderator, placed in a distance of ∼ 60 cm from the central fuel element inside the horizontal, through-going beam tube SR6, is currently under construction. It is supposed to generate UCN densities of 1000 - 10000 UCN per cubic centimeter in up to four connected experiments. This talk will give an overview of...
The Proton Electron Radiation Channel (PERC) experiment will investigate the decay of the neutron by observing spectra of the emerging electrons and protons, and several correlations between neutron spin, and the electron, proton, and neutrino momenta. Its aim is in particular to improve on the parity violating beta asymmetry, and the Fierz term by an order of magnitude. PERC is under...
