POSITION POSTED:  AUGUST 24, 2021
SALARY RANGE:  $51,400 - $70,000 (AO)

Under the supervision of an Operations Crew Chief and senior Accelerator Operators, incumbent will be responsible for the safe operation of the Jefferson Lab accelerators, for delivering a high quality, high energy electron beam to support the Department of Energy Nuclear Physics program. The accelerator and its systems consist of several miles of ultra-high vacuum beam line, vacuum pumps, bending magnets, focusing and steering magnets, high energy power supplies, superconducting radio frequency cavities, lasers, low conductivity cooling water systems, 2°K refrigeration systems, invasive and non-invasive beam diagnostic and monitoring systems and a large distributed computer control system.

Accelerator Operators develop knowledge on the operations of a wide spectrum of accelerator systems. This knowledge is obtained from a combination of online training, on the job training and operational experience. An operator must have a strong self-motivated desire to learn. They must be willing to ask questions when needed but also able to dig in and figure things out for themselves if necessary. Upon hiring the incumbent will have 6 months to complete Accelerator Operator qualifications. This is a self-paced program based mainly online and includes demonstrated performance of various routine operator tasks. Most complete this training in a little over 4 months however your learning will not stop there as this is just the minimum to be safe and able to effectively contribute in the Control Room, it can take 2+ years to fully understand it all and even then there is always something new to learn.
Accelerator operations normally consists of monitoring and controlling systems via computer generated graphical interfaces. Operators use these controls to perform set up, testing, tuning and troubleshooting of the electron beam. Along with operating the accelerator and its systems, operators are also tasked to maintain accurate records of system performance and control room activities. Accelerator Operators must be able to perform well as a team with the other members on their shift. They must be able to share the duties of simultaneous operation of multiple experiments as well as effectively communicating information back and forth among those on their shift. They will be required to interact with technicians, engineers and scientists on a technical level to adequately explain system status or problems, receive, understand and carry out actions. Accelerator Operators must be able to think logically to solve problems, to look at symptoms, determine possible causes, develop a plan and carry out actions to work toward correcting the problem.

The accelerator operates 24/7 for periods of several weeks or months followed by periods of accelerator down time for maintenance and reconfiguration. During the accelerator operational periods operators work a shift schedule that includes alternate weekends with corresponding days off during the week. Over a 14 day/two week period, an operator will work seven days on-shift, the next seven days will contain three off-shift work days and four off days.
24/7 operations means ~75% of the time operators are the only ones on site to respond to any problems or emergencies that occur. They often use their knowledge to correct problems without additional assistance but if assistance is required, they can work with the system expert remotely or locally to correct the problem. They are trained in electrical safety allowing them to assist electrical groups with repairs after hours. They provide the initial response to emergencies such as smoke and fire alarms making the call as to if a real or false alarm, they investigate oxygen deficiency alarms as well as provide the local response to 911 calls supplying initial first aid and CPR if necessary.

Accelerator Operators are encouraged to work with their supervisor to find other productive tasks beyond operating the accelerator that are inline with their interests, skills, experience and training. It is during their off shift work days or accelerator non-operational periods where operators can work with various accelerator support groups on activities that can include installing, maintaining, upgrading, troubleshooting and repairing accelerator mechanical, electrical and electronic systems. If they have the knowledge and skills they can also work with a software group to develop software for display and control screens, develop control system drivers, scripts and control algorithms. Other tasks available include researching, writing and maintaining operation procedures and training material, assisting with the scheduling, coordinating and tracking maintenance between groups, statistically analyzing RF cavity parameters and making changes to cavity operations to improve performance.
