This is the latest run report from HBT-EP, The High-Beta Tokamak of Columbia University http://www.seas.columbia.edu/apam/hbtep/ The shot leader was shiraki. Applied static perturbations to more biased plasmas at full amplitude (before clipping). We now have data from about 20 biased plasmas (with and without perturbations), and analysis is underway. http://www.ap.columbia.edu/HBT-EP/fileread.php
