“…The discharge voltage U d = 5 kV, the pressure p = 5•10 -6 Torr and the grid potential U grid = 1 kV were selected on the base of the discharge features and corresponded to the mode when a negative axial current of charged particles was registered [4].…”

“…The source design with metal hydride cathode could be greatly simplified due to the discharge properties changing [3]. It appears that at high discharge voltages a flow of negatively charged particles including negative ions and electrons along with positive ions starts yielding along the external magnetic field [4]. Picking up the value of external magnetic field, electric supply and discharge dimensions one could achieve the situation when the current of positive ions will be much lower than the negative one.…”

The paper describes a method of negative hydrogen ions separation from axial flow of charged particles extracted from Penning discharge with a metal hydride cathode. For this purpose, an electromagnetic filter has been designed basing on numerical solution of motion equations of charged particles in the filter. The optimal parameters of the filter operation were determined for the effective registration of negative hydrogen ions extracted in axial direction. Performed calculations together with experimental verification shows that there are not more than 10% electrons in the registered H– current. This model could be applied for the interpretation of any experiments with H– ions separation from an axial flow of charged particles extracted from a source with cylindrical geometry.

The influence of metal hydride hollow cathode on a Penning ion source operation has been carried out. The feature of investigation is hydrogen injection only due to its desorption from metal hydride under ion-stimulated processes. The regimes of optimal discharge operation in the hollow cathode mode are determined. It has been revealed that the transition to the hollow cathode mode occurs at lower voltages, the discharge works without external gas supply, and the working pressure in the cell is set at the level determined by the discharge current. The supply of a negative bias to the metal hydride hollow cathode weakly affects the features of the emission of axial particles, although it allows the increase of plasma density near the metal hydride hollow cathode.
