摘　　要：^(40)Ca^(+) ions are successfully confined,under the cooling of a red-detuned laser,in a home-built microscopic surface-electrode(MSE)trap.With all electrodes deposited on a low-rf-loss substrate,our 500-μm-scale MSE trap is designed involving three potential wells and manufactured by the standard technique of the printed circuit board.Both linear and two-dimensional crystals of ^(40)Ca^(+) are observed in the trap after preliminary micromotion compensation is carried out.The development of the MSE trap aims at large-scale trapped-ion quantum information processing.
