Quadrupole Cryostats
This document outlines the preliminary design criteria and configuration details for the quadrupole cryostats utilized in the BTeV project at Fermilab. Key specifications include maximum allowable working pressures (MAWP) for single-phase, two-phase, and LN2 shield, along with operational pressures and heat loads to 4K. Various cryostat layouts, cross-sections, and support structures are presented, contributing to the effective functionality and safety of the BTeV systems. Detailed notes provide insights for engineers and researchers involved in the project.
