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

I am a Principal Research Physicist working in the Off-Site Collaborations Department
of the Princeton Plasma Physics Laboratory of Princeton University
The Princeton Plasma Laboratory home page is www.pppl.gov
The Princeton University home page is www.princeton.edu

I conduct research developing controlled thermonuclear fusion in Tokamaks as a less polluting 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.

The JT-60U home page is: http://www-jt60.naka.jaeri.go.jp/

Previously I collaborated on experiments in TFTR
