An improved elliptic guide concept for a homogeneous neutron beam without direct line of sight
C. Zendler, D. Nekrassov, K. Lieutenant
Ballistic neutron guides are efficient for neutron transport over long distances, and in particular elliptically shaped guides have received much attention lately. However, ellipti…
Design of a horizontal neutron reflectometer for the European Spallation Source
D. Nekrassov, M. Trapp, K. Lieutenant +3
A design study of a horizontal neutron reflectometer adapted to the general baseline of the long pulse European Spallation Source (ESS) is presented. The instrument layout comprise…
Bi-spectral beam extraction in combination with a focusing feeder
C. Zendler, K. Lieutenant, D. Nekrassov +2
Bi-spectral beam extraction combines neutrons from two different kind of moderators into one beamline, expanding the spectral range and thereby the utilization of an instrument. Th…
Design of a wavelength frame multiplication system using acceptance diagrams
D. Nekrassov, C. Zendler, K. Lieutenant
The concept of Wavelength Frame Multiplication (WFM) was developed to extend the usable wavelength range on long pulse neutron sources for instruments using pulse shaping choppers.…
Search for photon line-like signatures from Dark Matter annihilations with H.E.S.S
H. E. S. S. Collaboration, :, A. Abramowski +201
Gamma-ray line signatures can be expected in the very-high-energy (VHE; E_γ> 100 GeV) domain due to self-annihilation or decay of dark matter (DM) particles in space. Such a signal…
Identification of HESS J1303-631 as a Pulsar Wind Nebula through gamma-ray, X-ray and radio observations
The H. E. S. S. Collaboration, :, A. Abramowski +196
The previously unidentified very high-energy (VHE; E > 100 GeV) γ-ray source HESS J1303-631, discovered in 2004, is re-examined including new data from the H.E.S.S. Cherenkov teles…
