Endcap Calorimeter/Vessel Calculations

The end cap calorimeters's cryostate is composed of two vessels; one nested inside the other. Figure 1 shows a simplified sketch of the nested vessels. Drawings 3740.220-MD-222076 Rev. A shows the details of the inner vessel. Drawing 3740.220-MD-222075 Rev. A shows the details of the outer vessel. As shown in figure 1, the cryostate consists of ten different geometric parts. The parts labeled 1-4 are cylindrical shells, the parts labeled 5 and 6 are common torispherical heads and the parts labeled 7-10 are unique heads.
