摘要:

We have developed a versatile, pulsed source of cold(&Dgr;E=0.018eV), low-energy positrons(E≈0–9 eV). Multiple pulses of105positrons, each 10&mgr;s in duration, are extracted from a thermalized, room temperature positron plasma stored in a Penning trap. The frequency, duration, and amplitude of the pulses can be varied over a wide range. ©1997 American Institute of Physics.
