The study of heavy ion stopping dynamics using associated K-shell
projectile and target radiation was the focus of the reported experiments.
Ar, Ca, Ti, and Ni projectile ions with the initial energies of 5.9 and
11.4 MeV/u were slowed down in quartz and arogels. Characteristic
radiation of projectiles and target atoms induced in close collisions was
registered. The variation of the projectile ion line Doppler shift due to
the ion deceleration measured along the ion beam trajectory was used to
determine the ion velocity dynamics. The dependence of the ion velocity on
the trajectory coordinate was measured over 70–90% of the ion beam
path with a spatial resolution of 50–70 μm. The choice of
SiO2 aerogel with low mean densities of 0.04–0.15
g/cm3 as a target material, made it possible to stretch the
ion stopping range by more than 20–50 times in comparison with solid
quartz. It allowed for resolving the dynamics of the ion stopping process.
Experimentally, it has been proven that the fine porous nano-structure of
aerogels does not affect the ion energy loss and charge state
distribution. The strong increase of the ion stopping range in aerogels
made it possible to resolve fast ion radiation dynamics. The analysis of
the projectile Kα-satellites structure allows supposing that ions
propagate in solid in highly exicted states. This can provide an
experimental explanation for so called gas-solid effect.
The article presents a source producing high-power ultrawideband
electromagnetic pulses. The source includes a generator of
monopolar pulses, a bipolar pulse former, and a combined
ultrawideband transmitting antenna. Monopolar 150-kV, 4.5-ns
pulses are transformed into bipolar 120-kV, 1-ns pulses, which
are emitted by the antenna. The pulse repetition rate of the
setup is up to 100 Hz. The peak power of the source is 170 MW
as measured with a TEM-type receiving antenna having 0.2–2
GHz passband. The pattern width of the transmitting antenna
at a half-level of peak power is 90° and 105° for the
H- and E-planes, respectively. The electric field strength measured
4 m from the transmitting antenna in the direction of the main
radiation maximum is 34 kV/m.
Primary storages based on a linear transformer scheme were
developed long ago. In this scheme, the secondary turn only
has to be insulated from the high output voltage. Seven years
ago at the High Current Electronics Institute (HCEI) a primary
storage based on a linear transformer scheme and called the
Linear Transformer Driver (LTD) stage was designed. In LTD stages,
the primary turn, the storage capacitors with the switches,
the core, and the outer conductor of the secondary turn are
integrated into the stage cavity representing one separate building
block of the primary storage. The body of the LTD cavity keeps
ground potential during the shot allowing us to assemble them
in series or in parallel depending on load requirements. Such
flexibility of the storage structure and high output power of
the LTD stages allows us to replace for some applications the
traditional water line technology with LTD-based primary storages
that are connected directly to the load (Direct Drive
Scheme—DDS). In this article, we present the design of
several LTD stages developed at HCEI and give examples of
high-power energy storages produced by using the LTD technology.
