D0 Silicon Upgrade: Upgrade on Cryogenic Lines at Refrigerator
This is an upgrade to the thermal contraction analysis sound in D0 Engineering Note: 3823.115-EN-426. In this new design, a portion of the transfer lines are consolidated into one 6-inch vacuum jacket. Since all four transfer lines follow the same path and are of equal lengths, the stress analysis is performed on only one transfer line using the design system ALGOR{reg_sign}. The GHe Cooldown Supply line is analyzed for combined pressure, thermal movement, and dead weight and all the stresses were below the allowable stress limit of 25,050 psi.
