摘要: We have investigated motional heating of laser-cooled ${}^{9}{\mathrm{Be}}^{+}$ ions held in radio-frequency (Paul) traps. measured rates a variety traps with different geometries, electrode materials, and characteristic sizes. The results show that is due to electric-field noise from the trap electrodes exerts stochastic fluctuating force on ion. scaling rate size much stronger than expected spatially uniform source (such as Johnson external circuits), indicating microscopic uncorrelated patch-potential fields) more likely candidate for heating.
