Abstract: The EPED model has been designed to predict the pedestal height and width from a minimal set of parameters and using the stability of the pedestal region for global MHD peeling-ballooning (P-B) modes as well… read more here.

DOI: 10.1088/1741-4326/aa98f4
Abstract: The effects of plasma shaping, in particular triangularity (δ), on temperature fluctuations in the tokamak a configuration variable have been studied using the correlation electron cyclotron emission system. It has been found that, in ohmic… read more here.

DOI: 10.1088/1741-4326/abdb95
Abstract: Magnetically confined fusion plasmas with negative triangularity (δ) exhibit greater L-mode confinement than with positive δ. Recent experiments in the TCV and DIII-D tokamaks have correlated the confinement improvement to a reduction of fluctuations within… read more here.
