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.…
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…
