Collider dipole magnet field angle measurement

Methods and devices for measuring the prototype Superconducting Super Collider (SSC) dipole magnetic field angle with respect to a vertical reference are discussed. An internal research and development project was conducted to develop a low-cost device for production measurement of the SSC dipole field verticality. The system employs Hall probes, a level sensor, and precision electronics interfaced to a personal computer to perform this critical measurement at discrete points along the magnet beam axis. Specification, component selection, mechanical and electrical design, calibration, and test results are presented
