A velocity selector (2) acts as broad band energy filter on the incoming ... lowering the general neutron background in the experimental zone. It is followed by the Virtual Source, a heavy slit with horizontal variable ...

and parasitic scattering from the monochromator and its environment. To this end a velocity selector (2), acting as a broadband filter suppressing neutrons with wavelength of λ/2, λ/3 etc. will be placed ... casemate. The incident beam casemate as well as the monochromator will be enclosed in a massive shielding consisting of a sandwich of lead ...
