This article describes the principles of operation and the parameters of the SINUS setups designed at the Institute of High-Current Electronics, Siberian Division, Russian Academy of Science, over the period from 1990 to 2002. A characteristic feature of accelerators of the SINUS type is the use of coaxial forming lines (in particular, with a spiral central conductor) which are charged by a built-in Tesla transformer to produce the accelerating high-voltage pulses. This ensures a reasonable compactness and long lifetime of the setups.

Voltage Pulses

At RFNC-VNIIEF on the basis of a “Gamma-1” high-current pulsed accelerator there is being developed a four-module “Gamma-4” electrophysical facility. A synchronization system of the "Gamma-4" facility is meant for a simultaneous (with precision not worse than ±3 ns) triggering of high-volt gas-filled trigatron type switches of modules' pulse forming systems (144 items, operating voltage ≤ 1 MV), modules' pre-pulse switches (24 items, ≤ 3 MV) and 8 Marx generators (40 items, ≤ 100 kV). The synchronization system comprises 54 pulse generators, involving 25 generators on the basis of water insulated forming lines with distributed parameters and multi-channel gas-filled switches. On matched cable loads with resistances 0.45 Ohm these generators form voltage pulses with amplitudes 100 kV with durations 25 ns. A jitter of switches of these generators does not exceed ± 2 ns. To raise the amplitude of pulse drivers of pulse forming system switches and pre-pulse switches of modules in the facility synchronization system there are used step-up transformers based on pulsed high-voltage cables.

Linear Transformer Driver

AbstractLinear transformer driver (LTD) technology is actively developed at the Institute of High Current Electronics in Tomsk, Russia. This technology is being examined for use in high current high voltage pulsed accelerators. Recent development of high voltage low inductance capacitors and low inductance switches enabled to achieve ~100 ns rise time of the LTD output pulse. This technique allows one to eliminate intermediate pulse forming sections, used in the present accelerator technology, which would keep the footprint of an LTD accelerator small. LTD based drivers are currently considered for many applications, including future very high current Z-pinch drivers for inertial confinement fusion, medium current drivers with adjustable pulse length for isentropic compression experiments, and finally relatively low current accelerators for radiography and X-pinches. In this article, we present the design and test results for a new LTD stage, that operates at 100 kV charging voltage. Current amplitude up to 850 kA with ~140 ns rise time was obtained on a 0.05 Ω load. Stack of the LTD stages can be easily assembled in series or in parallel, thus providing voltage or current multiplication, respectively. Design of multi-mega-volt and multi-mega-ampere generators becomes straightforward with the LTD technology.
