JYFLTRAP [1] is a double Penning trap setup located at the accelerator laboratory of the University of Jyväskylä. It has been built for measuring atomic masses of short-lived isotopes produced using the IGISOL method [2], which is fast and enables the extraction of any element, including refractory ones. Until the summer of 2010, before the setup was shut down for upgrade, masses of about 300 short-lived nuclei ranging from 10C to 203Bi were measured, many of them for the first time.
In this contribution, an overview of JYFLTRAP mass measurement is given with emphasis on the most recent work. These include tests of the conserved vector current hypothesis (CVC) [3], nuclear structure studies on the neutron rich side of the nuclide chart [4], and decay energy measurements of double β decay emitters and double electron capture candidates for neutrino studies [5].
