Titel: Weak Interaction Physics at SARAF


In this talk I will review the current status of the radioisotopes trapping program at the Soreq Applied Research Accelerator Facility (SARAF), and prospects for measurements at the upgraded accelerator: SARAF-II.

In our new lab complex, situated above the SARAF target room, we utilize two systems: An electrostaticion-beam-trap,designed for trapping various radioactive ions, starting with 6He; and a magneto-optical trap, which is designated for various rare neon isotopes, starting with 23Ne.

Both traps are equipped with novel designs for the detection of recoiling particles from nuclear β-decay and precise measurements of the kinematic correlations between them. These correlations are sensitive to scalar- and tensor-current interactions which are suggested by some beyond standard model (BSM) theories [2]. Bounds on exotic interactions from the precision and high-energy frontiers are interpreted in the framework of a model-independent effective field theory approach [3].
