It is shown, that in electromagnetic plasma lenses moment aberrations obey the conservation law of the moment of the ion generalized momentum; they disappear when an ion source is placed in a zero magnetic field. Geometrical ...

The anomalous Doppler effect (ADE) in systems consisting of an electron beam and slow wave structure in longitudinal magnetic field is considered. Resonance condition for amplifiers and generators based on ADE enables ...

For three types of electrostatic lenses the focusing length is proportional, accordingly, to the second-, or first-, or half-power of the parameter representing the relation of a charged particle accelerating potential to ...

In this work the studies of long uniform, and non-uniform modified adiabatic plasma lenses of different types are performed that intended for middle and high energy ion beam focusing.

It was shown experimentally that beam-plasma discharge (BPD) in the system of electron beam plus plasma (created by the beam) does not “wait” the condition np>>nb, that connected with the instability increment usually used ...

In case of gas pressure increasing, the plasma density rapidly increases at p=(1-2)*10⁻⁴ Torr, due to the beam-plasma discharge start (BPD). For fixed pressure above 2*10⁻⁴ Torr, the BPD start depends from the interaction ...

Using an open barrel-shaped resonator (OBR) plasma density, produced by a sequence of duration 2 μs of relativistic electron bunches, each of energy 4.5 MeV and charge 0.16 nC, in air at pressure of 10…60 Torr was measured. ...

In magnetoelectrostatic plasma lenses the strength and spatial distribution of the magnetic and electric fields were optimized for maximum beam current density in the focal plane. Experimental implementation of the ...

At present there is a significant requirement for the development of devices for focusing high-energy intense ion beams for the solution of actual scientific and technological problems (inertial thermonuclear fusion on ...

An estimation for power requirements and efficiency of a linear accelerator with transverse focusing by an electron beam is presented for the following parameters: proton beam current of 100…300 mA, output energy of 3 ...
