title = "Injection of hydrogen and ethylene at the plasma edge of TJ-II: A comparative study",
abstract = "Injection of H2 and C2H4 through mobile limiter and into different magnetic configurations has been performed in TJ-II ECH plasmas. - Little plasma contamination by ethylene is seen under most conditions. - A factor of 7 less Ha emission than in H2 puffing is produced from ethylene cracking. - Locally deposited carbon layers drive enhanced contamination when limiter is inserted at the plasma edge. - Small fuelling efficiency is consistent with previous reported data for other hydrocarbons5. - Strong hydrogen built up in deposited layers associated with ethylene injection has been deduced. - All these observations agree with prompt cracking and ionization of injected hydrocarbon, leading to local carbon layer deposition.",
