## About Positron Dynamics

VC Fund · Port Angeles, United States

Positron Dynamics LLC was founded in 2011 by Ryan Weed and Joshua Machacek. Our area of expertise is in the use of ‘cold’ positrons as a diagnostic for materials and in low-energy collisions with atoms and molecules. The company develops positron beam technologies for use in non-destructive testing (NDT) of critical components in the aerospace anddefense markets. At the heart of these technologies is a novel method of producing and moderating positrons, for which several patents were awarded in 2011.
