Hall D Cryogenic requirements

This document outlines the installation and operational requirements for the Hall D Cryogenic System featuring superconducting coils immersed in liquid helium. The system is designed to handle nominal operations at 1500A, involving a 40-year-old magnet and its solenoid coil test setup. Key preparations for full current tests and simultaneous load assessments in the test lab and Hall D Cryo Can are detailed, inventorying the readiness of necessary hardware, support structures, and power supplies by mid-June.
