Abstract
We experimentally proved the feasibility of a liquid-based
target for Laser Ion Source (LIS) application. The target consists
of melted metal gallium contained in a heated crucible. Ions current
resulting from laser irradiation. Moreover, given the explosive
ablation mechanism involved, each laser shot has been found to
induce fluctuations in the surface level. It takes about 0.7 sec to
recover the steady condition fully. Despite the maximum fluctuation
being 2.7 mm (top-bottom maximum displacement), these fluctuations
have shown no significant influence on total ion current and are
independent of the temperature of the sample within the tested
repetition rate. This study provides valuable insights into the
potential of employing such a system for LIS.
