The Atomic Defectscope has been installed on the beamline dedicated to materials science analysis on the GBAR development platform. It benefits from the positron beam produced by the first non-radioactive positron source, developed during the SOPHI ANR and SELMA ASTRE projects. Positron annihilation Doppler broadening spectroscopy is used to characterize defects in the studied matter.
The Atomic Defautscope was jointly funded by the Departmental Council of Essonne, CEA Irfu, BPI France and POSITHÔT.
