Project summary

Imploding Z-pinch which is created in a diode of high-current generator is efficient X-ray source.

The purpose of the project is both theoretical and experimental investigations of Z-pinch soft X-ray source for various applications such as sub-micron resolution X-ray lithography. X-ray microscopy for biology studies and others.

Scientists from NITP. MIEP and RIPT are experienced in impulse soft X-ray sources. Some X-ray diagnostics and measuring equipment and technology that are needed exist in the institutes. The theoretical model of plasma, numerical codes will be developed at NITP. Simulations of experimental installation and its load, modification of the installation, spectral- and time-dependent measurements of X-ray emission, experimental data receipt will be carried out at NITP. Diagnostics for measurements of spatial and time-dependent radiation from Z-pinch will be created at NIEP. The optic and X-ray streak camera design for investigations of Z-pinch dynamics will be developed at RIPT.

It is supposed that the dependence of soft X-ray source parameters from load configuration (single wire, wire array, gas-puff and so on), load materials, generator parameters and their optimization for higher efficiency will be carried out.

A part of questions for X-ray source creation can be decided using high-current generator SIGNAL existing at NITP. But some modification and necessary equipment are required for experimental installation SIGNAL that demand funds from ISTC.

During the work the soft X-ray installation, Z-pinch numerical code and measuring equipment including electrotechnical, X-ray and optical technique will be created.

As a result "of the proposed activities significant research and development progress toward the creation of plasma with needed parameters: density, homogeneity, ion state and so on and matching of high-current generator, plasma opening switch and imploding plasma load will be accomplished.

In the course of this non-military work, scientists and engineers from NITP, NIEP and RIPT will contact with colleges from civilian sectors all over the world. The realization of this project will familiarize them with problems having further scientific and commercial potential for the future.

Discussion and review activities will occur quarterly.
