Techniques include: In 2003 DIII-D began experimenting with resonant magnetic perturbations to control ELMs.
[9] In 2006 an initiative (Project Aster) was started to simulate a full ELM cycle including its onset, the highly non-linear phase, and its decay.
As of late 2011, several research facilities had demonstrated active control or suppression of ELMs in tokamak plasmas.
For example, the KSTAR tokamak used specific asymmetric three-dimensional magnetic field configurations to achieve this goal.
[12] In 2022, researchers began testing the small ELM hypothesis at JET to assess the utility of the technique.
