D0 Silicon Upgrade: Estimates of the Deflections and Stresses of the Toshiba Cold Mass Support System

PDF Version Also Available for Download.

Description

Tensile stresses in the Toshiba cold mass support links generated by the loadings the coil is subject to, and the deflections the coil experiences as a result of these loadings, are estimated. The axial links are conservatively designed and it should be reasonably easy to ensure that the three links at each end of the coil carry approximately equal loads. Small deviations from this ideal should not have great consequence as a system-of-three is somewhat forgiving in this regard. The use of preload makes the north operating deflection equal to the smaller south operating deflection, possibly a convenience when the ... continued below

Description

Tensile stresses in the Toshiba cold mass support links generated by the loadings the coil is subject to, and the deflections the coil experiences as a result of these loadings, are estimated. The axial links are conservatively designed and it should be reasonably easy to ensure that the three links at each end of the coil carry approximately equal loads. Small deviations from this ideal should not have great consequence as a system-of-three is somewhat forgiving in this regard. The use of preload makes the north operating deflection equal to the smaller south operating deflection, possibly a convenience when the nozzle design is contemplated. Toshiba has indicated they will establish the desired preload using strain gauges near the warm ends of the links.
