Experimental investigation of the low molecular weight fluoropolymer for the ultracold neutrons storage
C. Düsing, P. Geltenbort, C. Plonka +1
The experimental setup for examining the low-molecular-weight fluoropolymer CF(CF-O-CF-O-(CFCF, which is a promising coating material for th…
A source of ultra-cold neutrons for the gravitational spectrometer GRANIT
P. Schmidt-Wellenburg, P. Geltenbort, V. V. Nesvizhevsky +4
We present the status of the development of a dedicated high density ultra-cold neutron (UCN) source dedicated to the gravitational spectrometer GRANIT. The source employs superthe…
First observation of KL -> pi+- e-+ nu e+ e-
KTeV Collaboration
This letter is the first report of the KL -> pi+- e-+ nu e+ e- decay. Based on 19208+-144 events, we determine the branching fraction, B(KL -> pi+- e-+ nu e+ e-; Mee > 5 MeV/c^2, E…
A direct experimental limit on neutron -- mirror neutron oscillations
G. Ban, K. Bodek, M. Daum +22
In case a mirror world with a copy of our ordinary particle spectrum would exist, the neutron n and its degenerate partner, the mirror neutron , could potentially mix and…
Replika Mirrors - Nearly Loss-Free Guides For Ultracold Neutrons
Christian Plonka, Peter Geltenbort, Torsten Soldner +1
The reflectivity of ultracold neutron (UCN) guides produced with a dedicated technique called {\sc Replika} has been studied. The guides are made of nickel, where the surface quali…
Efficient extraction of a collimated ultra-cold neutron beam using diffusive channels
P. Schmidt-Wellenburg, J. Barnard, P. Geltenbort +4
We present a first experimental demonstration of a new method to extract a well-collimated beam of ultra-cold neutrons (UCN) from a storage vessel. Neutrons with too large divergen…
