Efficient transport of cold atoms or ions is a subject of increasing concern in many experimental applications reaching from quantum information processing to frequency metrology. Different transport schemes have been developed, which allow to move single atoms minimizing their energy gain. In this work, the experimental implementation of the transport of an ion cloud in a macroscopic linear radiofrequency (RF) trap is discussed. Numerical simulations done by molecular dynamics are carried out, which take into account realistic experimental potentials in order to design a method to shuttle large ion samples in a very short time. The deformation of the trapping potential and the spatial extension of the cloud during transport appear to be the major sources for the energy gain of the ions. The efficiency of transport in terms of transfer probability and ion number is also discussed.
