An accelerator operator controls a particle accelerator during an experiment. A particle accelerator is a complex machine used in physics research that conducts charged particles at near light speed in confined beams. As an accelerator operator, you work directly with the physicist or research team running the experiment and ensure that all the parameters of the experiment are accounted for and set. Your duties and responsibilities are to calibrate the systems, review the schedule, make any adjustments to the particle beam before running the test, and help analyze the outcome.
