| Description | Journal: Nuclear Fusion The dependence of the H-mode energy confinement time $τ_{E}$ on the plasma elongation and the divertor configuration is studied. A regression analysis of the H-mode database is presented in which the dependence on the closed/open divertor configuration, estimated from the ASDEX experiments, is included. The dependence of $τ_{E}$ on the elongation factor k is found to be positive (approximately $k^{0.6}$) for ELM-free H-mode discharges, in accordance with experimental results for ELM-free limiter H-mode plasmas in JFT-2M. In addition, the influence of the X-point configuration (single null or double null) on the confinement time is briefly addressed |
