Dresden EBIT at Weizmann Institute of Science

The EBIT installed at the Israeli Weizmann Institute of Science is a modified Dresden EBIT featuring a direct, nearly closed gas injection system into the drit tube assembly for maximum trapping and ionization efficiency while working with low gas flux rates without diminishing the bunching phase space of the source. This is a necessary precondition in order to exploit even tiny amounts of rare isotopes.

The experimental aim of the setup is the precise determination of the beta-neutrino correlation in the decay of radioactive nuclei to probe fundamental interactions for possible deviations from the Standard Model of particles and fields. Therefore, helium-6 with a half-life of only 0.8 s is ionized inside the EBIT and then sent towards a Paul trap for lifetime measurements.
