摘要:

A ballistic method is presented for transferring positron plasmas emanating from a region with a low magnetic field and relatively high pressure into a 15 K Penning‐Malmberg trap immersed in a 3 T magnetic field with a base pressure of the order of 10−13mbar. Subsequent stacking resulted in a plasma containing 4.2 × 108positrons. Using a rotating wall electric field a plasma containing 90 million positrons was compressed to a density of 3.6 × 109cm−3. © 2003 American Institute of Physics
