Undergraduate Research Assistant

Overview

PPPL is seeking a undergraduate student intern to work on a mostly computational project related to estimating the radiated power for a new tokamak fusion plasma device called SMART in Seville, Spain. PPPL is assisting SMART with diagnostics to measure radiation from the plasma in SMART. We also have a code which can calculate radiated power from the main hydrogen gas in the plasma as well as possible impurities (metals from the wall, for example). The distribution of heavy impurities in the plasma can be asymmetrical due to centrifugal effects if the plasma is rotating at a significant speed. This rotational effect is also accounted for in the code, but the plasma rotation needs to be estimated separately. The rotation arises mostly from momentum imparted by the plasma heating method: neutral beam injection. Providing calculations of the expected rotation and radiated power to the SMART team will be important for their interpretation of diagnostic measurements in the device.

A U.S. Department of Energy National Laboratory managed by Princeton University, the Princeton Plasma Physics Laboratory (PPPL) is tackling the world’s toughest science and technology challenges using plasma, the fourth state of matter. With more than 70 years of history, PPPL is a leader in the science and engineering behind the development of fusion energy, a potentially limitless energy source. PPPL is also using its expertise to advance research in the areas of microelectronics, quantum sensors and devices, and sustainability sciences. Whether it be through science, engineering, technology or professional services, every team member has an opportunity to contribute to our mission and vision. Come join us!

Responsibilities

Core Duties

The successful candidate will be responsible for learning how to use the radiated power code (Python based), working with scientists in Spain to obtain various planned plasma scenarios (plasma shape, temperature, density, etc…) that are used as inputs, and obtaining estimates of the plasma rotation to understand the centrifugal effect on impurity concentration and therefore on radiated power. The student will be involved in meetings with scientists at PPPL and remotely with those in Spain.

Additionally, opportunities exists for the student to participate in a summer Introduction to Plasma and Fusion course (half days for two weeks in June), to present their results in a student poster session at PPPL at the end of the summer in August, and potentially to attend and present results at the APS Division of Plasma Physics meeting in November in Long Beach, California (depending on funding availability).

Qualifications

Education and Experience

• Current undergraduate student in good standing in physics or engineering.

Knowledge, Skills and Abilities

• Experience with Python is necessary. Experience with presenting research results in a group setting is desirable.
