We report on a system to generate and trap these species in the laboratory. Laser ablation of a solid target (LiH) facing a sublimating Ne matrix generates cold electrons, anions, and cations. Axial energy distributions (of e$^-$, H$^\\pm$ and Li$^\\pm$) peaked at 0-25 meV are obtained in a Penning trap at 90 mT and 0.5 eV barrier. Anions can be guided and neutralized with low recoil energy by near-threshold photodetachm","authors_text":"Alvaro N. Oliveira, Claudio Lenz Cesar, Daniel M. Silveira, Levi O. A. Azevedo, Rodolfo J.
