Posted: 11/25/2025
Location: Princeton Plasma Physics Laboratory (PPPL), Princeton, NJ, with collaboration in Naka, Japan

Overview

The successful candidate will lead the development, calibration, operation, and data analysis of the X-ray Imaging Crystal Spectrometer (XICS) on the JT-60SA tokamak. This diagnostic will be used to study particle, thermal, and momentum transport in advanced plasma scenarios. The role involves combining experimental expertise with theory, computational modeling, and a rigorous verification & validation framework, collaborating with international teams in Europe and Japan.

JT-60SA Highlights:

• Largest and most powerful tokamak currently in operation

• Superconducting, long-pulse capable, with advanced plasma shaping and control

• Supports ITER and future fusion reactor research under the Broader Approach collaboration

Responsibilities

• Lead XICS implementation and maintenance on JT-60SA

• Perform day-to-day calibration, operation, and 3D X-ray tomographic data analysis

• Develop and maintain data analysis codes for diagnostic interpretation

• Participate in experiments and collaborate with European/Japanese researchers

• Supervise Ph.D. students or postdocs, and disseminate results through publications and conferences

Qualifications

Required:

• Ph.D. in plasma physics, fusion science, atomic physics, or related field

• Strong experimental experience on fusion devices

• Expertise in tokamak diagnostics, X-ray measurements, and core plasma physics

Preferred:

• Proficiency in modern X-ray tomographic programming techniques

• Research experience in thermal, impurity, and momentum transport, MHD equilibrium, beam/RF heating and current drive

• Knowledge of Japanese is a plus but not required

Additional Information

• Weekly Hours: 40

• Probationary Period: 180 days

• Benefits: Comprehensive benefits program available

• EEO Statement: Princeton University is an equal opportunity employer; all qualified applicants will receive consideration without regard to protected characteristics
