摘要：

Both ion and electron temperatures in the scrape-off layer ( SOL) of the Tore Supra tokamak were measured by a retarding field analyzer during an ohmic density scan. SOL T-i was found to be higher than T-e by a factor of 4-7. The ion-to-electron temperature ratio tau decreases with increasing density. Core T-i and T-e measurements in Tore Supra combined with a multi-machine database of tau measurements show that tau > 1 also in the edge of the confined plasma and increases with radius.
