Lawrence Berkeley National Laboratory

A decay and timing detector for superheavy elements has been developed at Lawrence Berkeley National Laboratory with the goal to become the main measurement detector of FIONA. It combines a double-sided silicon strip detector that provides decay energy and position information with a microchannel plate detector which determines the implantation time of the nuclei on the detector through the detection of secondary electrons emitted from the silicon detector upon impact. This new setup was simulated, constructed and tested offline, in a proof-of-principle setup using a beam of 216Po + , the results of which are presented in this work. The new detector provides, for the first time in FIONA, sensitivity to isotopes beyond α emitters (and fissioning isotopes) and decay time information.
