Abstract
The behavior of ionic species formed by the laser ablation of the superconducting Y1Ba2Cu3OX targets has been investigated by the time-of-flight mass spectroscopic analysis (TOF-MS). The ambient pressure has been found to influence the velocity distribution of ions in the plume. As the pressure increases, all ion velocities except for that of O+ ion decrease. The velocity distribution of each ion at high oxygen pressure fairly match with that of the supersonic expansion model. The distribution width narrows as the ambient pressure decreases. The temperatures associated with the velocity distribution width of the ionic species increase as the ambient pressure increases. The increase is due to the interaction between the expanding ions and the ambient gas.
