Purpose of the lab:

Main goal:

To investigate new, more efficient ionization pathways for atoms in RILIS experiments. For this, autoionizing states of atoms need to be mapped out through laser spectroscopy.

Secondary goals:

Questions related to fundamental atomic spectroscopy, e.g. accurate determinations of atomic ionization potentials.

LARIS labLARIS lab

Experimental method:

Multi-step laser ionization spectroscopy on laser-ablated stable isotopes, using up to three simultaneously tunable 10 Hz solid-state lasers for the ionization.

Sources: Smalley-type ablation source (rotatingmetal rod with pulsed valve); Effusive oven source.

Detection: Time-of-flight mass spectrometer.
