  7. 6 He + Fig. 2 A schematic view of the EST for b - decay studies. The radioactive ion, like 6 He, moves with E k -4.2 keV between the reflecting electrodes. The b electrons are detected in position sensitive counters while the recoiling ions, due to kinematic focusing, are detected with very high efficiency in either one (determined by the instantaneous direction) of the annular MCP counters. Apparent advantages: • “Natural” additional kinetic energy of recoils. Kinematics focusing. • Large solid angles (for BOTH ion recoil and electrons • Field- free and “equipment - free” inner region • Simplicity, portability • Complementary to other method (different systematic errors) • Full reconstruction of event-by-event - actually measure cos( q )!

B) 6 He atoms are transferred to an EBIT where they get ionized, accumulated, and bunched and guided C) The ion bunch is injected into the EIBT for beta-decay studies. D) Data acquisition: signals from detectors are processed, recorded, and analyzed . Michael Hass IFMIF/ELAMAT 2016

  9. Trapping and bunching of stable 4 He + and 4 He ++ . As expected, the trapping time of 4 He ++ is shorter than that of 4 He + . Bunching R&D with 4 He • • Algorithm and tests of a position-sensitive e-detector R&D into specialized design of Electron Beam • Ion source Michael Hass IFMIF/ELAMAT 2016
