Study of the helium metastable state population in the plasma-beam discharge with an extended hollow cathode
T he results of experimental study of populations of metastable states of helium atoms in transversal nanosecond plasma-beam discharge with a hollow cathode within the range of gas pressures of 1-100 Torr are described. The research was carried out in the discharge without magnetic field, with the application to the discharge of transversal magnetic field. The regularities in the changes of population states of helium atoms under application of external magnetic field are discussed.
