"Direct laser cooling of negative ions has not yet been achieved. An important potential application of\r\nthis technique is the use of cooled negative ions to sympathetically cool antiprotons. Antihydrogen,\r\nsynthesized from cold antiprotons, is suitable for fundamental studies tests of CPT symmetry and the\r\nweak equivalence principle with antimatter.\r\nDuring this work, the negative lanthanum ion was identified as a good candidate for laser cooling\r\nusing in-flight spectroscopy. Lanthanum anions were produced as a beam with a kinetic energy of a few\r\nkeV and were excited using a tunable laser. The light radiation was superimposed to the ions both in a\r\ncollinear and in a transverse setup to study the laser cooling transition.\r\nTrapping of anions both in a Penning trap and in a Paul trap was demonstrated as a prerequisite to\r\nincrease the interaction time of anions and light towards the first realization of laser cooling. Detailed\r\nstudies were performed both traps to find the best conditions for anions capture. All trap parameters were\r\noptimized with a view to a high capture efficiency as well as optimal properties of the confined plasma."^^ . "2018" . . . . . . . "Giovanni"^^ . "Cerchiari"^^ .
