A professional who controls operation of particle accelerator used in research experiments involving properties of subatomic particles. Responsibilities include:

• Reviews experiment schedule to ascertain particle beam parameters specified by experimenter (scientist), such as energy, intensity, and repetition rate.
• Communicates with accelerator maintenance personnel to ensure readiness of support systems, such as vacuum, water cooling, and radiofrequency power source.
• Sets control panel switches, according to standard procedures, to route electric power from source and direct particle beam through injector unit.
• Turns panel controls and watches meters and panel lights to adjust beam steering units and direct beam to accelerator.
• Pushes console buttons in prescribed sequence to control beam path in accelerator.
• Adjusts controls to increase beam pulse rate, energy, and intensity to specified levels.
• Notifies experimenter in target control room when beam parameters meet specifications.
• Pushes control levers to steer beam to experimenter's target, as directed.
• Monitors readings at console during experiment to ensure accelerator systems meet specifications and notifies experimenter of condition.
• Alters beam parameters during experiment as directed.
• Ensures that maintenance workers vacate hazardous locations before operations.
• Records data in log relative to beam specifications, equipment settings used, and beam conditions obtained for future reference.
• Participates in maintenance and modification of systems as member of team.
• May be designated according to type of accelerator operated.
