Abstract
The effective conditions of MAR and the physical mechanism have been investigated by solving a set of time-dependent rate equations numerically. Preliminary results show that the effect of MAR becomes small in the high density of background plasma. This is due to lack of vibrational molecules available for MAR. The vibrational molecules are destroyed through IC and DA before reaching the sufficient density for MAR when a flow rate of hydrogen molecular source is not sufficient. In fact, the effect of MAR is appeared remarkably when the flow rate increases by an order of magnitude. These results indicate that not only the plasma density but also the flow rate of hydrogen molecules are important parameters for the onset of MAR.
