摘要：
Kinetic analysis of the behaviour of hydrocarbons in fusion plasmas requires knowledge of cross sections for their most relevant collision processes. Upgrades and extensions of the commonly used HYDKIN (HYDride KINetics) online cross section database (based on compilations in 2002) and its data analysis toolbox for collisions of hydrocarbons with electrons and protons in relevant fusion plasma conditions are presented. Newly identified channels for dissociative recombination provide strongly reduced D/XB ratios for Gero-Band spectroscopy at low temperatures compared to earlier results, in accordance with experimental findings.
