Design and Assembly of a Magnetic Quench Protection System for Alpha-G
The gravitational behavior of antimatter has critical bearing upon our understanding of particle physics, quantum gravity, and the expansion of the universe. The weak equivalence principle (WEP) states any particles gravitational acceleration is the same, conflicting with quantum theory, which imposes limits on the certainty of position and momentum (thus trajectory) of particles. ALPHA-G, a new antimatter gravity experiment being performed at CERN, tests how gravity acts upon antihydrogen as a test of the WEP. Confining and cooling antihydrogen such that gravitational rather than thermal effects are measured requires strong magnetic fields produced by superconducting coils kept at liquid helium temperatures. These coils, when heated, lose their superconductivity and expends stored energy into heat, damaging the magnet and potentially the entire experiment. I will research and design magnetic quench protection systems for the experiment. This entails designing circuits to detect quenches, choosing instrumentation equipment to measure magnet characteristics, and helping to build the magnet portions of ALPHA-G.
