Fig. 3: Comparison of shots using time-variable beam energy to alter beam ion instabilities. Energies from the co-current tangential beams identified as (a) 30L and (b) 330L. (c) Ratio of the measured neutron rate over the TRANSP-calculated classically expected rate. Cross-power of line-integrated electron density fluctuations from shots (d) 166400 and (e) 166401.
