Ultracold negative ions — •Jan Meier — Max-Planck-Institut für Kernphysik, Postfach 103980, 69029

Currently no technique exists which allows the cooling of negative ions to a temperature lower than that of the surrounding trap. Laser cooling of negative osmium ions holds the prospect of achieving temperatures well below 1 mK. Cooling antiprotons with this technique might open the door to forming antihydrogen at ultra-cold temperatures, thus allowing precision antimatter studies.
