Advanced Neutron Instrumentation at FRM-II

The construction of the new German high flux neutron source FRM-II is finished and FRM-II is waiting for its licence to start nuclear operation. With the beginning of the routine operation 22 instruments will be in action, including 5 irradiation facilities and 17 beam tube instruments, most of them use neutron scattering techniques. Additional instruments are under construction. Some of these ...

Renovation of Ge-Crystal Monochromator for Neutron Scattering Spectroscopy

Neutron scattering spectroscopy is a powerful probe to study phonon and magnon excitations in condensed matter physics. A development of neutron monochromator, which properly branches monochromatic neutrons from a white beam, is therefore one of the instrumental key issues in neutron science; especially, due to the lack of neutron beam flux. Ge and Si single crytals have been one of the typical...

Neutron Scattering Instrumentation

This chapter gives a short introduction into neutron scattering instrumentation to allow the non-specialist reader to acquire the basics of the method necessary to understand the technical aspects in the topical articles. The idea is not to go into details but to elaborate on the principles as general as possible. We start with a short discussion of neutron production at large-scale facilities....

Performance of the Double Multilayer Monochromator

A tunable, double multilayer x-ray monochromator has recently been implemented on the National Synchrotron Light Source (NSLS) X25 wiggler beam line. It is based on a parallel pair of tungsten-boron-carbide multilayer films grown on silicon substrates and purchased from Osmic, Inc. of Troy, Michigan, USA. It acts as an optional alternative to the conventional double silicon crystal monochromato...
