The Princeton Plasma Physics Laboratory is a world-class fusion energy research laboratory managed by Princeton University for the U.S. Department of Energy’s Office of Science. PPPL is dedicated to developing the scientific and technological knowledge base for fusion energy. The Laboratory advances the fields of fusion energy and plasma physics research to develop the scientific understanding and key innovations needed to realize fusion as an energy source for the world. 

The Princeton Plasma Physics Laboratory currently uses two (2) large, stored energy, Motor-Generators, each Generator rated at 450 MVA, to supply power to the various experimental loads in support of NSTX-U operations. Each motor-generator is driven by a 15,000 HP electrical induction motor rated at 13.8 KV. The motor-generator operator-technician will operate the motor-generators and will provide support for all maintenance, testing, repairs, upgrades, installations, modifications and troubleshooting of the motor generators and their associated subsystems. 


  • Provides Motor-Generator technical support as a technician for NSTX-U operations and for daily/monthly/annual maintenance of subsystems.
  • During run periods, perform the duties of operator of the MG System.
  • During maintenance periods, perform maintenance on the MG System, including supervision of other technicians.
  • Supports the maintenance and real-time troubleshooting of the Motor Generator’s cycloconverters, excitation systems, liquid rheostats, instrumentation calibrations and controls, HV and MV (Medium Voltage) circuit breakers, switchgear, distribution systems and protective devices. Participate in planning for upgrade of subsystems.
  • Records and documents MG system performance data in accordance with established PPPL procedures and guidelines.
