AN INTERNATIONAL PELLET ABLATION DATABASE

The contents are described of an international pellet ablation databas e (IPADBASE) that has been assembled to enable studies of pellet ablat ion theories that are used to describe the physics of an ablating fuel pellet in a tokamak plasma. The database represents an international effort to assemble data from several tokamaks of different magnetic co nfigurations and auxiliary heating methods. In the initial configurati on, data from JET, Tore Supra, DIII-D, FTU, TFTR, ASDEX Upgrade, JIPP T-IIU, RTP and T-10 have been included. The database contains details of measurements of deuterium and hydrogen pellet ablation, including p ellet mass and speed, plasma electron density and temperature profiles , and pellet ablation light emission. A summary of the database conten ts and a scaling analysis of the data are presented.
