Research Plan: Positron trapping

• Start by demonstrating ability to confine energetic electrons

  • No radioactivity
  • Can inject low energy electrons from heated W wire by thermionic emission
  • Use ECRH at 2.45 GHz (B=0.0875 T) to heat the electrons and confirm ability to confine 5 keV electrons

• Develop methods of injecting high energy electrons

• Then initiate positron program

  • Deal with safety issues regarding radioactivity
  • Use experience with electrons to develop efficient ways of loading the trap with positrons from Na-22 source
