Figure 3
(Left) Sketch of the Fermi chopper at MARIA. The Fermi chopper is based on two aluminium barrels coated by 10B in epoxy. The omitted coating is indicated by the dashed rectangular regions on the right side of the FC. The larger window is used for [\Delta\lambda/\lambda = 3\%] and the slimmer window for [\Delta\lambda/\lambda = 1\%]. Both barrels are driven by a single motor. (Right) The Fermi chopper installed on the vertical lift, for changing between the neutron guide (on top of the Fermi chopper) and the two different wavelength resolutions.
