an immediate opening for an Accelerator Physics Research Assistant to join our team.
The High Repetition-rate Electron Scattering apparatus (HiRES) is based on a unique electron accelerator using the latest radiofrequency and laser technology to produce very short bursts of electrons, then used in the subsequent beamline for ultrafast electron diffraction experiments. The machine is currently undergoing an intense period of development and experimental activity. The main goal of the instrument is to provide stable electron beam probes to the experimental station, with spatial and temporal characteristics tailored to the particular experimental need. To this end, our group is working on beam dynamics simulations and developing high precision instrumentation and controls for the particle accelerator and for the laser system, that will add new capabilities and result in improved beamline performance.
You will join the accelerator team effort towards more reliable and automated beamline operation, and performing beam dynamics simulations for beamline optimization and fast switching between operating modes. You will also be part of the ongoing effort in beamline tuning, modeling and experimental characterization, with the final goal of enabling high fidelity predictions of electron beamline characteristics at the sample position.
What You Will Do:
Operating the HiRES electron accelerator.
Optimization of electron beam trajectory along the beamlines, develop routines for automated alignment.
Develop new Matlab-based routines for experimental beam measurements and characterization
Run electron beam dynamics simulation for theoretical prediction of electron beam parameters along the beamline, and perform beam measurements to match experimental and simulated data. Create input files for the simulation tools providing high-fidelity prediction of the beamline.
Participate in group and team meetings.
Maintain lab notebook and detailed instrumentation and sample logs.
Follow EH&S guidelines to ensure the safety of self and others in the lab office spaces.
What Is Required:
Basic theoretical knowledge and practical experience with (some) of main electron accelerator components, such as RF high power amplifiers, electron sources, electromagnets, electron beam diagnostic and laser systems.
Proficiency with basic data acquisition and analysis coding using scientific programming languages (Matlab, Python, etc...)
Working experience with particle accelerator science and technology and applied physics.
Extremely detail-oriented with excellent communication, writing and troubleshooting skills.
Additional Desired Qualifications:
Bachelor's Degree in Physics, Engineering or related field.
Experience in image and waveform-based fast feedback loops.
Basic knowledge and understanding of electron beam dynamics theory, with and without space charge.
Experience with electron beam dynamics codes, such as ASTRA and GPT.
Familiarity with low noise RF signals characterization tools and techniques, such as spectrum analyzers.
Experience in magnetic measurements.
Experience in image acquisition and analysis.
Basic familiarity with Machine Learning algorithms.
The posting shall remain open until the position is filled.
This is a full time, 1 year, term appointment with the possibility of extension based upon satisfactory job performance, continuing availability of funds and ongoing operational needs.
Full-time, M-F, exempt (monthly paid) from overtime pay.
Salary is commensurate with experience.
This position may be subject to a background check. Any convictions will be evaluated to determine if they directly relate to the responsibilities and requirements of the position. Having a conviction history will not automatically disqualify an applicant from being considered for employment.
Work will be primarily performed at Lawrence Berkeley National Lab, 1 Cyclotron Road, Berkeley, CA.

About Lawrence Berkeley National Laboratory
In the world of science, Lawrence Berkeley National Laboratory (Berkeley Lab) is synonymous with excellence. Thirteen scientists associated with Berkeley Lab have won the Nobel Prize. Fifty-seven Lab scientists are members of the National Academy of Sciences (NAS), one of the highest honors for a scientist in the United States. Thirteen of our scientists have won the National Medal of Science, our nation's highest award for lifetime achievement in fields of scientific research. Eighteen of our engineers have been elected to the National Academy of Engineering, and three of our scientists have been elected into the Institute of Medicine. In addition, Berkeley Lab has trained thousands of university science and engineering students who are advancing technological innovations across the nation and around the world. Berkeley Lab is a member of the national laboratory system supported by the U.S. Department of Energy through its Office of Science. It is managed by the University of California (UC) and is charged with conducting unclassified research across a wide range of scientific disciplines. Located on a 200-acre site in the hills above the UC Berkeley campus that offers spectacular... views of the San Francisco Bay, Berkeley Lab employs approximately 4,200 scientists, engineers, support staff and students. Its budget for 2011 is $735 million, with an additional $101 million in funding from the American Recovery and Reinvestment Act, for a total of $836 million. A recent study estimates the Laboratory's overall economic impact through direct, indirect and induced spending on the nine counties that make up the San Francisco Bay Area to be nearly $700 million annually. The Lab was also responsible for creating 5,600 jobs locally and 12,000 nationally. The overall economic impact on the national economy is estimated at $1.6 billion a year. Technologies developed at Berkeley Lab have generated billions of dollars in revenues, and thousands of jobs. Savings as a result of Berkeley Lab developments in lighting and windows, and other energy-efficient technologies, have also been in the billions of dollars. Berkeley Lab was founded in 1931 by Ernest Orlando Lawrence, a UC Berkeley physicist who won the 1939 Nobel Prize in physics for his invention of the cyclotron, a circular particle accelerator that opened the door to high-energy physics. It was Lawrence's belief that scientific research is best done through teams of individuals with different fields of expertise, working together. His teamwork concept is a Berkeley Lab legacy that continues today.
