Outline of Final Research Achievements |
Toward the formation of electron-positron plasmas in a laboratory, experiments with intense slow positron beam were conducted in a dipole magnetic configuration. In a prototype dipole experiment with a permanent magnet, operated at the NEPOMUC positron facility, 100% lossless injection into closed magnetic surfaces, trapping for more than 1 s, and orbit manipulation were demonstrated for 5 eV positron beam. Based on these experimental results, development of a levitated dipole experiment was conducted, including the levitation system, efficient direct cooling of a high temperature superconducting (HTS) coil winding, fabrication of HTS coils to be used for the confinement of plasmas.
