Özet

Design, construction and experiments of the 3 kJ Mather type plasma focus device is described in order to carry out fusion researches. This device is especially established for neutron yield and fast neutron radiography by D-D reaction which is given by D + D→3 He (0.82 MeV) + n (2.45 MeV). Preliminary results which are found in air atmosphere are given with the focus parameters. Experiments have shown that more than 125 kA peak current at 15 kV flows between electrodes for each shot which are operated in 17 mbar air pressure. Structural neutron shielding computations for safety has been completed and the setup is covered by paraffin walls with 40 cm thickness in order to thermalise the 2.45 MeV neutrons for near future radiography studies.
