The industrial production of the simplest form of antimatter, the positron, antiparticle of the electron, opens new horizons


The aim of POSITHÔT is to bring positron annihilation spectrometry as an industrial tool to move nondestructive techniques towards defect and damage measurement.

Thanks to the non-radioactive positron production technique, developed at CEA Saclay and industrialized by POSITHÔT, this aim becomes a reality.

Issued from fundamental research at the Research Institute for the Fundamental Laws of the Universe (IRFU, Institut de Recherche sur les Lois Fondamentales de l’Univers ) from the CEA (ATOMIC ENERGY COMMISSION), POSITHÔT keeps strong links with the GBAR experiment, aiming at the direct measurement of the gravitational constant of antihydrogen.

The interest shown by the materials science community to the positron generator highlighted the potential application that had not been identified by fundamental physicists.

Jean-Michel Rey decides to develop these industrial applications.
