Abstract

The aim of this paper is to review recent progress in the study of pools of ions trapped below the surface of superfluid 4He. A brief description will be given of the way in which the ions are trapped, and it will be explained why the study of the behaviour of the pools is of interest. Two recent experiments will be described in more detail: a study of the ripplon-limited mobility of the ions at very low temperatures; and the detection and study of the Wigner crystallization of the pools. Both these experiments are interesting in their own right, but they relate also to the behaviour of capillary waves or ripplons on the surface of the helium and are therefore relevant to one particular type of excitation associated with the helium.
