“…The stream of accelerated electrons generated by the pulsed electron accelerator ASTRA-M developed in Tomsk Polytechnic University was used to expose the aluminum nanopowder. The kinetic energy of electrons was up to 360 keV [10][11][12]. The scheme of aluminum nanopowder irradiation experiment is shown in Fig.…”

The influence of the electron beam irradiation on the parameters of aluminum nanopowder oxidation by heating in air was studied. It was found that the oxidation starts at the temperature in the range from 410° C to 460° C and independent on the radiation dose. The degree of oxidation varied from 44.4 % to 58.3 % and its dependence on the radiation dose was not established. The heat energy release occurred in two stages: at the first stage (up to ~ 660° C) in general the increase of the thermal effect was observed. At the second oxidation stage of irradiated aluminum nanopowder the growth of the thermal effect also observed. The peak of heat effect achieved by irradiation (45.0 kGy absorbed dose) was 2576 J/g higher than the thermal effect for non-irradiated aluminum nanopowder. The energy stored is an additional motivating factor in the synthesis of composite materials, intermetallic compounds, hydrogen producing reactions and synthesis of various kinds.

“…A pulsed generator of accelerating voltage of the ASTRA-M accelerator [12] allows one to generate voltage pulses with the amplitude of up to 450 kV and duration of 350-600 ns. Pulse repetition rate of 100 pps became available when using a fabricated switch with an automatic start system described elsewhere [13]. The ASTRA-M accelerator is capable to inject an electron beam in a long time mode with a repetition rate of 40 pps with flowing water cooling of an exit window membrane [14].…”

Paper presents the results of experiments on multicapillary carbon-epoxy as a candidate material for a cathode of a pulsed electron accelerator. A high voltage pulse of 350 kV, 350 ns (FWHM) was applied to the cathode. The pulse repetition rate was 20 pps. The optical image of the cathode surface after 4×104 shots of electron beam was changed as well as electrical characteristics of the electron diode.

“…In particular, resonant microwave compressors are used in studies of microwave pulses influence on electronic devices and their element base [5], in radiolocation [6], in accelerator technology [7] and a number of other scientific and technological applications For these applications, the resonant microwave compressors provide performance comparable in level with a power compressors based on multi-stage PFN with transitional energy storage devices, such as [8]. In contrast, the resonant microwave compressors can provide a high repetition rate without using of expensive high-voltage switches with special frequency systems of their triggering [9].…”

The work presents the results of theoretical and experimental studies of the formation of microwave pulses with the adjustable power, duration, repetition rate and the envelope form during energy output from the cavity by controlled transformation of the oscillation mode at the waveguide stub coupling aperture. Pulse parameters are changed by adjustable elements of the coupling of modes, which directly affect to the coefficient of the coupling of modes h. The possibility to form a series of subnanosecond MW pulses at a fractional energy output and nanosecond pulses of various pulse duration at a single complete output of high frequency energy from the compressor cavity is demonstrated. The envelope of the pulses is calculated through the recurrence relations between the amplitudes of waves in the system, the relations between which have been recorded according to the scattering matrix method. Using this approach on passive X-band RF pulse compression system, we obtained power gain of 8-9 dB, 8-10 ns pulse duration at 9.248 GHz.
