Abstract

Trapped radioactive atoms and ions have become a standard tool of the trade for precision studies of beyond SM physics. β decay studies, in particular, offer the possibility of detecting deviations from standard model predictions of the weak interaction which signal new physics. These 'precision frontier' searches are complementary to the high energy searches performed by the LHC and other high energy/high luminosity facilities. I will present a general overview of magnetooptical and optical traps and their use for weak interaction studies. I will further present both the Berkeley 21Na trapping experiment and the new Hebrew University 17-25Ne trapping program, recent experimental results, and future plans.

Biography

Guy Ron graduated 2009 from Tel Aviv University working with Prof. Eli Piasetzky on high precision measurements of proton form factor ratios at the Thomas Jefferson National Accelerator Facility CEBAF Accelerator. After a short postdoc at the Weizmann Institute jointly with Prof. Micha Hass and Prof. Nir Davidson he moved in Mid- 2009 to the Lawrence Berkeley National Lab to work with the late Prof. Stuart Freedman on high precision measurements of the beta decay of trapped atoms and ions. In 2011 Dr. Ron took up a position as an assistant professor at the Hebrew University of Jerusalem. His current research interest include: high precision measurements of the beta decay of trapped neon and helium isotopes, accelerator based measurements of nucleon charge and magnetization densities and radii, and positron annihilation spectroscopy as a probe of material and surface structure.
