Abstract
At present, the GDT facility of the Budker Institute Novosibirsk, which is an axially symmetric magnetic mirror device of gas dynamic trap type, is being upgraded. The first stage of the upgrade is the Synthesised Hot Ion Plasmoid (SHIP) experiment. The experiments will be performed in a small mirror section that is installed at one side of the GDT. The magnetic field on axis will be in the range of 1-7 T and the mirror ratio will amount 1.2-1.4. The mirror is filled with background plasma streaming in from the central cell. Two neutral beam injectors perpendicularly inject a total current up to 120 equ. Amperes of hydrogen atoms with an energy of 25 keV as pulse with a duration of about 1 ms. Ionisation of the beams generates the high-energetic ion component with the high density and mean energy about 17 keV. The plasma bata ~ 0.8. This contribution explains the concept of the SHIP experiment and presents the results of SHIP simulation. The first experimental activity is also presented.
