Description
We are investigating the use of laser-cooled anionic molecules to sympathetically cool antiprotons confined in the same trapping potential, which is of interest for antimatter experiments at CERN. A test setup to produce cold ground state C2- molecules is currently being commissioned.
This setup will be presented, together with a theoretical study on the feasibility of several laser cooling schemes, including one using the AC-Stark shift.
Laser cooling of anions --- which has so far never been achieved --- would also enable the sympathetic cooling of any other negatively charged species, opening new opportunities in a variety of research areas.
