Figure 13
Horizontal slices through the butterfly geometries. (a) BF1 geometry. (b) BF2 geometry. The dark-blue volumes are para-hydrogen and the turquoise volumes are water. The proton beam is incident from the right. The focal point for the North sector is indicated with a red spot. The views of the cold and thermal sources are illustrated for the North beamport at 60° with respect to the proton beam, as for Fig. 12. |
