The possibility of increasing the current of negative hydrogen ions extracted in the longitudinal direction from a Penning discharge with a metal hydride cathode by reducing the anode-cathode distance is shown. The features ...

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 ...

The paper describes a method of negative hydrogen ions separation from axial flow of charged particles extract- ed from Penning discharge with a metal hydride cathode. For this purpose, an electromagnetic filter has been ...
