The positron facility provides a wide range of capabilities, including high-current beams for investigation of bulk materials properties, low-emittance beams for studies of one-component plasmas, and a positron microprobe.

Experiments underway at the positron facility are probing the mechanisms by which defects arise in materials, of vital importance for science-based stockpile stewardship in this era of a comprehensive ban on nuclear weapons testing.

The positron facility at LLNL is designed to produce positrons with a wide range of characteristics, and to deliver them to a number of experimental apparatuses. The electron linac can produce very intense pulsed beams of positrons, while the pelletron can produce DC beams at high energies with a very narrow energy distribution.

These beams are transported to experiments, including a positron trap for particle physics research and a positron microprobe for high-resolution materials science.
