Survey/Shipment Workflow • Cornell ships vacuum chamber to BNL. • BNL assembles magnets and chamber to plate. • BNL ships assembly at left to Cornell (un-surveyed). • Cornell receives Rexroth stand assembly from outside vendor. • Cornell joins plate to Rexroth stand. • Cornell does survey and positioning of magnets relative to chamber. • Cornell surveys/positions stand plate into ring.
