Description

The JET H-modes characteristics are investigated. Analysis of X-ray emission signals, interferometric and LIDAR measurements of density are performed; and ECE and LIDAR measurements of electron temperature and pressure profiles are carried out. The results are consistent with the magnetic equilibrium, shows that JET H-modes may be characterized by a long non-steady state condition with unconventional density and pressure profiles which are flat or hollow within the q=1 surface, which expands after the L to H transition. The integrals of plasma current (I) and helicity (K) are used to describe JET H-modes as states of constrained minimum energy. Theoretical and experimental data are compared
