Ultracold-neutron infrastructure for the gravitational spectrometer GRANIT (2008)
Schmidt-Wellenburg, P., Andersen, K. H., Courtois, P., Kreuz, M., Mironov, S., Nesvizhevsky, V. V., ...
The gravitational spectrometer GRANIT will be set up at the Institut Laue Langevin. It will profit from the high ultracold neutron density produced by a dedicated source. A monochromator made of...
Zimmer, O., Schmidt-Wellenburg, P., Assmann, M., Fertl, M., Klenke, J., Mironov, S., ...
We report experiments on the production of ultracold neutrons (UCN) in a converter of superfluid helium coated with fluorinated grease. We employed our technique of window-free extraction of...
A superfluid helium converter for accumulation and extraction of ultracold neutrons (2007)
Zimmer, O., Baumann, K., Fertl, M., Franke, B., Mironov, S., Plonka, C., ...
We report the first successful extraction of accumulated ultracold neutrons (UCN) from a converter of superfluid helium, in which they were produced by downscattering neutrons of a cold beam from the...
