4. Outside coursework alone, have you personally developed, materially modified, or owned electromagnetic, particle in cell, beam physics, or plasma simulations used for research or engineering decisions? *

YesNo

5. Can you independently write numerical research or engineering code in Python, C++, Julia, MATLAB, or an equivalent technical language? *

YesNo

8. Describe the most technically difficult electromagnetic, beam, or plasma simulation you personally built or owned *

9. Describe a model you validated against an analytic result, published benchmark, or experiment. How close was the agreement, what initially disagreed, and what did you learn? *

10. A simulation predicts excellent device efficiency, but experiment is substantially worse. What numerical artifacts, missing physics, and experimental effects would you investigate before trusting either result? *
