Picture showing Rohacell foam support structures for the silicon barrel waters. Although both shapes (C vs L) were once considered, it was decided to utilize the "C" shaped pieces to facilitate assembly and maintenance of the barrels. These Rohacell sections were machined at UCR. Details of the thermal characteristics of these Rohacell cages can be found in: PHENIX-MVD-94-2, PHENIX-MVD-95-11, and PHENIX-MVD-94-12.
