Welcome to Robert Budny's home page (http://w3.pppl.gov/~budny)

I am a Principal Research Physicist working in the Tokamak and ITER Division
of Princeton University's Princeton Plasma Physics Laboratory

The Princeton University home page is www.princeton.edu

The Princeton Plasma Laboratory home page is www.pppl.gov

I conduct research developing controlled thermonuclear fusion in Tokamaks as a potential energy source

Much of my current research uses the TRANSP plasma analysis code and the GS2 and GYRO gyrokinetic microturbulence codes
The TRANSP homepage is w3.pppl.gov/transp
The GS2 homepage is gs2.sourceforge.net
The GYRO homepage is http://fusion.gat.com/comp/parallel/gyro.html

I have also been applying these codes to understand transport in JET, DIII-D, and JT-60U plasmas.

Previously I collaborated on experiments in TFTR
