Radio-frequency wall conditioning for steady-state stellarators
Results of numerical modelling of a pulsed discharge used for wall conditioning and sustained by excitation of slow waves at frequencies below the ion cyclotron are presented. The analysis carried out with usage of a selfconsistent model that simulates plasma production. The numerical calculations...

Digital Library of Periodicals of National Academy of Sciences of Ukraine| Резюме: | Results of numerical modelling of a pulsed discharge used for wall conditioning and sustained by excitation of
slow waves at frequencies below the ion cyclotron are presented. The analysis carried out with usage of a selfconsistent
model that simulates plasma production. The numerical calculations have shown that at the plasma buildup
stage, the atoms are generated mainly owing to dissociation of hydrogen molecules by electron impact. When the
RF power is off the dissociative recombination of molecular ions with electrons comes to play that is an additional
source of atomic hydrogen. |
