Abstract
The δ-kick cooling of ions trapped in the diffusion mode of the linear electrostatic trap was demonstrated. Both the shape and the height of the cooling pulse were chosen based on the results of the one-dimensional model presented. Although the correlation between ion velocity and position within the bunch was assumed to be near linear, the one-dimensional model can be easily extended to other types of correlation. The experimental results indicate that when the cooling pulse is timed correctly, the diffusion of the ion bunch is reduced, while the average velocity and the number of ions in the bunch remain unchanged.
