Edge ion-to-electron temperature ratio in the Tore Supra tokamak

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 Ti was found to be higher than Te by a factor of 4–7. The ion-to-electron temperature ratio τ decreases with increasing density. Core Ti and Te measurements in Tore Supra combined with a multi-machine database of τ measurements show that τ > 1 also in the edge of the confined plasma and increases with radius.

トーレ・シュプラ Tokamak のスクレイプオフ層(SOL)におけるイオン温度と電子温度の両方を、オーミック密度掃引中に減速電場分析器を用いて測定した。SOL の Ti は Te より 4〜7 倍高いことが判明した。イオン温度と電子温度の比 τ は密度の増加とともに減少する。トーレ・シュプラにおけるコアの Ti と Te の測定を、τ の測定に関する多装置データベースと組み合わせると、τ > 1 は閉じ込めプラズマの端部でも成り立ち、半径とともに増加することが示される。
