Beam path inside the monochromator drum, from the neutron source onto the monochromator.  Some of the wedges of the monochromator drum are shown in a cutaway view.  The tube that transports the neutron is stationary, and the wedges rotate with the drum and open to slide past the beam tube.  A guide field is included in the design in the event that the ³He polarizers can be used in the high flux polychromatic incident beam.
