dc.description.abstract | A new 1D radial fluid code, IMAGINE, is used to simulate the penetration of gas into a
tokamak plasma during a massive gas injection (MGI). The main result is that the gas is
in general strongly braked as it reaches the plasma, due to mechanisms related to charge
exchange and (to a smaller extent) recombination. As a result, only a fraction of the gas
penetrates into the plasma. Also, a shock wave is created in the gas which propagates
away from the plasma, braking and compressing the incoming gas. Simulation results are
quantitatively consistent, at least in terms of orders of magnitude, with experimental data
for a D2 MGI into a JET Ohmic plasma. Simulations of MGI into the background plasma
surrounding a runaway electron beam show that if the background electron density is too high,
the gas may not penetrate, suggesting a possible explanation for the recent results of Reux
et al in JET (2015 Nucl. Fusion 55 093013). | es |
