Project summaryGoal of the study is to find the ways of solving some physical-engineering problems for transition of the plasma focus systems into the gigajoule energy range of their power supply sources and to develop the conceptual pulsed - high power - neutron source, En=14,l MeV, based on the TSP-tokamak power supply set.
Magnetic storages with the stored energy of about 1 GJ, at the multicascade power peaking, are included into MINIK power supply system. Further peaking occurs hi the very PF-chamber of rather large size (due to a radial cumulating of a plasma current sheath). The expected multistage principle of power peaking allows one to match the "slow" energy storages with the pulsed plasma loading.
The neutron source under development in its power supply exceeds the possibilities of the existing systems more than by the order of magnitude. It will provide an essential expansion opportunities to investigate, test and to select the materials for fusion and nuclear reactors. Its other applications under consideration are reprocessing of radioactive wastes, neutronografical studies of materials, and biological and medical experiments. The high power PF, as a source of concomitant x-ray radiation, will be used for lithography with high spatial resolution, for radiography of materials and for testing the electronic components.
Project realization will result in a more complete and deep comprehension of the current cumulating phenomena in PF and will allow one to precise the critical current value over which the transition into the ignition mode of a self-sustaining fusion reaction occurs.
The development of a multicascade inductive power peaking system will essentially expand the borders of magnetic storage utilization for the pulsed - high power - systems and will introduce a fundamental contribution to the pulsed engineering.
The proposed measures will serve for further expansion of collaboration among the countries, will assist in the conversion of an industrial - technical potential from the military purposes to the civilian ones.
A rich experience of engineers and scientists from TRINITI, VNIIEF, RRC KI in creation of unique - high current - facilities and hi the studies of fast processes, neutron and x-ray diagnostics included, is expected to be used -for realization of a scientific part of the program, for determining the neutron source parameters and for the search of ways for practical implementation of results. The model experiments on feasibility of Project parameters will be performed at the functioning and constructed facilities of the organizations-participants. The high power computer base allows one to realize full-scale theoretical-calculational studies of processes, 3D-problem to simulate the processes of production and stability for the complicated plasma column structure included.
