Outline of Final Research Achievements

To explore the physics of two-fluid plasmas, we superimpose pure ion plasmas with pure electron plasmas in the BX-U linear trap. Although the two-dimensional density profiles of the both plasmas are changed after the superimposition, it appears that they are not relaxed to one-fluid plasma. This result suggests that the produced two-fluid plasma is so robust that their macroscopic structure can be maintained for a while.
