摘要

Europium ions were trapped in a Paul trap. The trapped ions were detected electronically, which involved the damping of a weakly excited tank circuit across the trap electrodes, tuned to one of the ion frequencies in the trap. The storage time of the trapped ions was observed to be 8 s at 2.4 x 10(-6) Pa base vacuum. On cooling the ions with nitrogen as buffer gas at 1.8 x 10(-4) Pa and helium at 6.4 x 10(-5) Pa, the storage time improved to 41.4 s and 102.7 s respectively.
