A high-current EBIT for charge-breeding of radionuclides for the TITAN spectrometer

The TITAN (Triumf’s Ion Trap for Atomic and Nuclear science) Penning trap mass spectrometer will be located at ISAC/TRIUMF in Vancouver, Canada. It is designed for conducting high-precision mass measurements on radionuclides via the determination of the cyclotron frequency of the ions confined within the Penning trap. An essential component of the setup will be an electron beam ion trap (EBIT) which will allow charge breeding of the radionuclides prior to the actual mass measurement. Compared to singly charged ions, the investigation of highly charged ions (HCIs) yields higher accuracies and enables access to radionuclides with half-lives considerably shorter than 100ms. The working principle of an EBIT as well as the design of the TITAN-EBIT in particular will be described.
