The CUBIC structure is shown in Figure 7.
Figure 7: CUBIC mechanical design.
The 3D view is identical to that shown in Figure 6, except that the radiation plate and skins have been removed. The instrument resides within a rectangular box that sits on top of the SAC-B structure, and is supported by a framework of aluminum and stainless steel L struts fastened to the SAC-B structure at the corners. A thin baseplate encloses the bottom of the CUBIC experiment. Details of the mechanical design are provided in Appendix 1.
