ITER H-MODE CONFINEMENT DATABASE UPDATE

This paper describes an update of the H mode confinement database that has been assembled for the ITER project. Data were collected from six machines of different sizes and shapes: ASDEX, DIII-D, JET, JFT-2M, P BX-M and PDX. The updated database contains better estimates of fast i on energy content and thermal energy confinement times, discharges wit h RF heating, data using boronization, beryllium and pellets, more sys tematic parameter scans, and other features. The list of variables in the database has been expanded, and the selection criteria for the sta ndard dataset have been modified. We also present simple scalings of t he total and thermal energy confinement time to the new dataset.
