Job Description

We have multiple openings for Electronics Technologists to support the National Ignition Facility (NIF) Power Conditioning Systems operations and maintenance. 

NIF is the world’s most powerful laser system, capable of producing over 1.8 MJ of optical energy. You will operate the Power Conditioning System (PCS) and the Plasma-Electrode Pockels Cell (PEPC) systems using high-level computer controls following detailed procedures. The PCS employs one hundred ninety-two high voltage (24 KV), high-energy (1.7 MJ per module) capacitor bank modules used to power the large flash lamps in the NIF solid-state laser amplifiers. The PEPC system employs high voltage electronics and sophisticated controls hardware and software to implement an optical switch topology for the 192 beams of the NIF main laser.  These systems include: high voltage power supplies, pulsed power hardware and circuits, analog, and digital controls hardware and software, embedded computers and diagnostics.

You will be responsible for operating both systems remotely using Graphical User Interfaces (GUIs) and perform site maintenance across multiple engineering disciplines and in collaboration with the lead operators, shot directors, system managers and electrical engineering support personnel. Due to the vast and varying types of experiments, NIF is a 24/7 operational facility. You may be required to have shift flexibility which may include working alternating schedules, occasional overtime and/or weekends to accomplish goals These positions are in the Laser Systems Engineering and Operations (LSEO) Division, within the Engineering Directorate.
