Observation of Plasma Focusing of a 28.5 GeV Positron Beam
- SLAC
The observation of plasma focusing of a 28.5 GeV positron beam is reported. The plasma was formed by ionizing a nitrogen jet only 3 mm thick. Simultaneous focusing in both transverse dimensions was observed with effective focusing strengths of order Tesla per micron. The minimum area of the beam spot was reduced by a factor of 2.0 {+-} 0.3 by the plasma. The longitudinal beam envelope was measured and compared with numerical calculations.
