h-MODE是1982年就發現,30年前老掉牙的東西,後來德國把這台ASDEX
送給中國,中國搞了10幾年才複製出H-MODE ;水準之差,引人噴飯
======================================
One of these momentous events, probably one of the most important in the history of fusion research occurred on 4 February 1982. Experimenting on the ASDEX Tokamak at the Max Planck Institute for Plasma Physics (IPP) in Garching, Germany, the German scientist Fritz Wagner was confronted by a totally unexpected "transition" in the neutral beam heating experiment he was conducting. "It came out of nothing," recalled the recently retired 65-year old physicist during a recent visit to ITER. "It wasn't predicted, it just happened..."
What was soon to be known as the "H-mode" (H for High) appeared first as "a strong and sudden change in plasma characteristics:" as the plasma in ASDEX was being exposed to intense heating by the neutral beam, its confinement suddenly improved by a factor of two and the turbulences at the plasma edge all but disappeared. |
