In this article we present the design and test results of most powerful, fast linear transformer driver (LTD) stage developed to date. This 1-MA LTD consists 40 parallel RLC (resistor R, inductor L, capacitor C) circuits called ``bricks'' that are triggered simultaneously; it is able deliver $\ensuremath{\sim}1\text{ }\text{ }\mathrm{MA}$ current pulse with a rise time $\ensuremath{\sim}100\text{ }\mathrm{ns}$ into $\ensuremath{\sim}0.1\mathrm{\text{\ensuremath{-}}}\mathrm{Ohm}$ matched...
In the present study thermal structure evolution is reviewed for known nonlinear optical borates such as β-BaB2O4, LiB3O5, CsLiB6O10, Li2B4O7, K2Al2B2O7, and α-BiB3O6, based on single-crystal powder X-ray diffraction data collected over wide temperature ranges. Temperature-dependent measurements of further are presented first time: α-BaB2O4 (295–673 K), β-BaB2O4 (98–693 LiB3O5 (98–650 K) K2Al2B2O7 (98–348 K). addition to established criteria (NLO) properties crystals, here role anisotropy...
The rapid development of the chemistry fluorooxoborates is associated with their important role as valuable optical materials. In this work, we reported first two silver representatives the...
A new silver iodide borate, Ag 3 B 6 O 10 I, is presented as a promising solid-state electrolyte with δ ↔ γ β α cascade of the isosymmetric superionic phase transitions.
A series of Pr 3+ , Nd or Sm -doped Na 3 Gd(BO ) 2 (NGB) crystals has typical luminescence spectra with relative intensity reaching the maximum at 1 mol% for and 10 mol.% doping.
LTD stages are designed to be used as a primary energy storage in high power pulsed generators. Previously the with current rise time of 1000 ns and 450 were reported. Present report describes design test results stage that provides /spl sim/200 kA rising 100 matched sim/0.4 Ohm load.
An acentric borate family, Ag4B4O7X2 (X = Br, I), has been prepared by slow cooling stoichiometric melts in evacuated silica ampules. Their crystal structure is comprised of two porous interpenetrating frameworks and demonstrates a further development the "salt-inclusion" architecture toward "covalent-inclusion" structure. The (Ag2X)+ sublattice shows strong anharmonic vibrations. Thermal expansion strongly anisotropic because presence condensed rigid kernite boron-oxygen chains aligned...
Primary storages based on a linear transformer scheme were developed long ago. In this scheme, the secondary turn only has to be insulated from high output voltage. Seven years ago at High Current Electronics Institute (HCEI) primary storage and called Linear Transformer Driver (LTD) stage was designed. LTD stages, turn, capacitors with switches, core, outer conductor of are integrated into cavity representing one separate building block storage. The body keeps ground potential during shot...
Fast LTD technology looks promising for making the pulsed power generators some applications more compact and less expensive because it does not need any pulse forming lines to produce nanosecond output pulses. In report we present 1 MV generator that is being produced demonstrate capability. The designed deliver a MV, 125 kA, /spl sim/50 ns width at 80% of peak amplitude sim/8 Ohm vacuum diode. stored energy 14 kJ, footprint sim/ 2 m/sup 2/.
The linear transformer driver (LTD) technological approach can result in relatively compact devices that deliver fast, high current, and high-voltage pulses straight out of the LTD cavity without any complicated pulse forming compression network. Through multistage inductively insulated voltage adders, output pulse, increased amplitude, be applied directly to load. usual architecture [A. A. Kim, M. G. Mazarakis, V. Sinebryukhov, B.
