Abstract
In a method of focusing a beam of charged particles by means of a magnetic field which is generated by a current flowing through a plasma volume contained by an insulating tube extending between two opposite annular electrodes which produce the current in a pulsed form, the insulating tube has, with respect to the cross-section of the particle beam which passes therethrough a diameter so selected that the tube wall is disposed adjacent the limit of the penetration depth of the magnetic field into the plasma as constricted solely by the magnetic field generated between the electrodes.
