Conceptual design for G2 cave and G2 beam splitter inside the G2 hutch:

• G2 cave is accessed through a small sliding door from the back.
• All scattering targets (crystal, shutters) are encloed in lead-steel-laminate walls.
• Mono slides along a long y-translation to optimized exit angle range and to minimize sizes of shutters and window.
• Mono box is part of an continuous windowless He flight path for G3.
