Obsah
The quantum counting position sensitive pixel detector Timepix with per–pixel energy and time resolution enables to detect radioactive ions and register the consecutive decay chain by simultaneous position– and time–correlation. This spatial and timing coincidence technique in the same sensor is demonstrated by the registration of the decay chain 8He --> 8Li and 8Li --> 8Be --> alpha+alpha and by the measurement of the b decay half-lives. Radioactive ions, selectively obtained from the Lohengrin fission fragment spectrometer installed at the High Flux Reactor of the ILL Grenoble, are delivered to the Timepix silicon sensor where decays of the implanted ions and daughter nuclei are registered and visualized. We measure decay lifetimes in the range ≥ ms with precision limited just by counting statistics.
