Figure 12
Beam extraction options for the pancake moderator, illustrated for a beamline in the middle of the North sector, i.e. at 60° counter-clockwise with respect to the incoming proton beam, incident from the right. The focal point for the North sector is shown as a red dot. (a) Near-corner extraction, such that each beamport axis points at the nearest cold–thermal junction. (b) Far-corner extraction, in which each beamport axis is oriented towards the more distant cold–thermal junction. In each case, the beamport axis is shown as a dashed black line, and the shaded light-blue and pink areas indicate the views of the cold and thermal sources, respectively, which can be achieved by tilting the instrument axis by 1° with respect to the beamport axis. The view areas shown are 7 cm wide.
