Recent experiments with lithium ion and electron plasmas in the BX-U linear trap Available to Purchase

We produce independent pure lithium-ion (Li⁺) and electron (e⁻) plasmas that exhibit completely different fluid motions to experimentally explore two-fluid plasma state. Further, we simultaneously confine those plasmas in a nested trap. During these years, we extensively studied weakly magnetized Li⁺ ion plasmas not only experimentally but also numerically. Regarding diagnostic tools, we developed a new method of capturing images of Li⁺ ion and e⁻ plasmas in one attempt. Using the method, we are now accumulating the two images of Li⁺ ion and e⁻ plasmas before and after plasma mixing. Another finding was intermittention leakages that occur during the potential barrier closure. By considering experimental and numerical results systematically, we finally explained the mechanism for the observed ion leakages.
