Alpha Plasma Microwave Modeler

As the Alpha Plasma Microwave Modeler, you will own the physics simulation pipeline that connects our gyrotron sources to plasma performance. You will model the propagation, polarization, and absorption of millimeter waves in the Alpha stellarator guiding the design choices that determine how effectively we heat the plasma. You will sit at the interface between plasma physics, RF engineering, and systems design, working closely with the ECRH design lead, electromagnetic engineers, and academic partners to ensure that simulation insight drives hardware decisions. You will establish the simulation baseline by running ray-tracing and beam-tracing codes across the Alpha operating space, validating these against W7-X experimental data so that the results can drive the design of the Alpha ECRH launcher and gyrotron designs.

Responsibilities

Run ray-tracing and beam-tracing simulations of EC wave propagation and absorption using codes such as TRAVIS, RAYTRAX and more complex beam or full wave model codes; Develop an integrated modeling framework that couples wave deposition to transport codes, enabling temperature and density profile optimization and validation of the heating scenario performance; Build and maintain Python-based post-processing pipelines to automate scenario scanning and interface simulation outputs with the Alpha integrated design framework; Model Electron Cyclotron Current Drive (ECCD) and assess its ability to modify rotational transform and equilibrium in the Alpha quasi-isodynamic configuration; Contribute to design reviews, interface control documents, and technical reports to ensure simulation results are traceable and actionable

Requirements

PhD (or equivalent demonstrated expertise) in plasma physics, applied physics, or a related field, with a focus on plasma-wave interactions or RF heating of magnetically confined plasmas; Hands-on experience with at least one EC propagation or absorption code (TRAVIS, TORBEAM, C3PO, IPF-FD3D, or similar); Proficiency in Python for simulation scripting, data analysis, and visualization; comfort reading and modifying legacy Fortran or C/C++ code; Systems-thinking mindset: able to translate physics outputs into engineering requirements and hardware constraints; Strong team player, comfortable working across physics and engineering disciplines and with external academic partners
