This engineering note documents the thermal contraction analysis that was done for the D-Zero solenoid chimney. The analysis was done as support of the 'Design Report of the 2 Tesla Superconducting Solenoid for the Fermilab DO Detector upgrade.' The cryogenic LHE and LN2 lines were analyzed for combined pressure, thermal movement, and dead weight. The tubing was stress analyzed per ASME code for Pressure Piping, standard ANSI AS:ME B31.3, for eight combinations ofthermal loading. A commercial pipe stress analysis and design system by Algor{reg_sign} was used for the analysis. Stresses calculated were well below allowables. Based on the analysis, the cryogenic lines will be installed at an offset from the vacuum jacket centerline so that during steady state cold operation, the cryogenic lines will be in a proper location
