Collinear laser spectroscopy is a well-known technique to study nuclear ground state properties of short-lived nuclei with laser spectroscopy. We are operating a Collinear Apparatus for Laser Spectroscopy and Applied Physics (COALA), which is used as a development platform for high-voltage measurements aiming at an accuracy of < 1 ppm as well as advanced techniques to extend the reach of collinear laser spectroscopy. Very recently, COALA has been equipped with an electron beam ion source (EBIS), which gives us access to highly charged ions. The candidate will participate in the ongoing development of the collinear technique, optimizing e.g. ion-optical elements, ion beam diagnostic, single-photon detection or laser-spectroscopic techniques. He or she will gain hands-on experience in ion optics, ion trajectory simulations, UHV systems, laser spectroscopy and experiment control.
