AMMONX: A kinetic ammonia production scheme for EIRENE implementation

Until recently the EIRENE suite handled hydrogen chemistry (i.e. H atoms, H2 molecules, and H2+ molecular ions and their isotopomers). Extensions also exist for hydrocarbon chemistry, including CxHy species (H is any hydrogen isotope), but no kinetic scheme including NHx chemistry had been implement...

description Until recently the EIRENE suite handled hydrogen chemistry (i.e. H atoms, H2 molecules, and H2+ molecular ions and their isotopomers). Extensions also exist for hydrocarbon chemistry, including CxHy species (H is any hydrogen isotope), but no kinetic scheme including NHx chemistry had been implemented. After a benchmarking of available schemes and kinetic data, a reduced scheme including 50 reactive processes is presented here, implying a large set of N-bearing species (N, N2, N2+, NHx radicals and ions). This mechanism is a part of a more complete scheme of 130 processes also including the metastable states of N2 and N. In a first time, this scheme has been validated by comparison with independent experimental works. In a second time the scheme was used in Eirene suite to model a type-case. First results confirm that under tokamak conditions, ammonia is produced in significative amount after N2 injection in the sub-divertor volume.
