Higher density, yes, but at the cost of lower temperatures. So not as good. Nice but old new. With painfullll advertisement.

Through a new process called plasma-wall self organisation, the CAS researchers were able to keep the plasma stable at unprecedented density levels.
The latest breakthrough was detailed in the journal : Science Advances (https://www.science.org/doi/10.1126/sciadv.adz3040 )in a study titled ‘Accessing the density-free regime with ECRH-assisted ohmic start-up on EAST’.
