Abstract
Abstract The Laser Ion Source and Trap (LIST) provides a new mode of operation for the resonance ionization laser ion source (RILIS) at ISOLDE/CERN, reducing the amount of surface-ionized isobaric contaminants by up to four orders of magnitude. After the first successful on-line test at \{ISOLDE\} in 2011 the \{LIST\} was further improved in terms of efficiency, selectivity, and reliability through several off-line tests at Mainz University and at ISOLDE. In September 2012, the first on-line physics experiments to use the \{LIST\} took place at ISOLDE. The measurements of the improved \{LIST\} indicate more than a twofold increase in efficiency compared to the \{LIST\} of the 2011 run. The suppression of surface-ionized francium contaminants has enabled the first in-source laser spectroscopy of 217Po and 219Po.
