Compact Electron Linear Accelerator RELUS-5 for Radiation Technology Application
The electron linear accelerator for radiation
technology application is designed to meet
the following main requirements: 3-5 MeV
energy, 3-6 microsecond pulse width, and 1

kW average beam power. The accelerating system is a 0.5 m long S-band standing wave on-axis coupled biperiodic
structure. A 35-40 kV electron gun with spherical cathode is used as the injector. The RF generator is a 2.5 MW peak
power 4 kW average power magnetron. The generated frequency is stabilized by a high Q-factor accelerating system
connected into feed-back of the magnetron. The magnetron is fed by a compact 45-55 kV IGBT based modulator. The
accelerator is controlled through a PLC-based control system.
Power Positron Beams for Ultrahigh Quasi-electrostatic Potencial Generation
Our aim is to discuss a proposal of experiments
on generation of ultrahigh(Gev’s) V. Gorev (RRC)
quasi-electrostatic field potencials by means
of high power positron beams. It is capable of producing ultrastrong curl EB-fields (by laser), magnetic fieds
(megagauss field generation by explosives)and electric field strenth(by needle points). But the problem of ultrahigh
electrostatic potencial generation (really, more than a few tens Mev by VdeG) is unresolved now. The basic proposal
to use high power positron beam for the accumulation of the positive charge ("charge pumping") on a macroscopic
body, freely moving in high vacuum was discussed in connection with the development of an macroparticle accelerator
(see, for example, *). Later, modification of this concept was developed for generation of high power protons,
heavy ions and neutrals beams. The following issues will be under considaration in this report: 1) High current and
low emmittance positron soures**. 2) Conceptual disign and peculiarities of the positron accelerator for the charge
pumping. 3) Peculiarities of the charge pumping in the real case of usage of low current positron beam. 4) Ultrahigh
quasi-eletrostatic potentials for fundam

Complex for X-ray Inspection of Large Containers
The X-ray inspection complex is intended for
non-intrusive inspection of large containers
in the seaport. The complex has been developed,
manufactured, and tested. To provide
two projections of irradiated container and
ensure reliable inspection, the complex in-

cludes two sets each containing self-shielded X-ray source and L-shaped detector array. The X-ray source includes
electron linear accelerator with 7.3 MeV energy, conversion target, local radiation shielding, and alignment means.
The accelerator uses standing wave bi-periodic structure fed by magnetron generator with 2.8 GHz frequency. It
provides intensive electron beam without application of external magnetic field for the beam focusing. This feature
makes it possible to use massive local radiation shielding made from iron. The radiation shielding provides large
attenuation of scattered X-rays and ensures the radiation safety for personnel as well as high sensitivity of detecting
system and good penetrability of the complex.
