✦ Synopsis

A carbon-cluster ion source based on laser ablation and ionization of a carbon sample has been built and tested for the JYFLTRAP setup. In the present configuration the ion source is situated in the electrostatic switchyard in front of the radiofrequency (RFQ) cooler and buncher. In this position the beam quality of the carbon clusters injected into the Penning trap system is considerably improved by the RFQ. Moreover, the mass-dependence of the RFQ's transmission can be used to some extent to suppress unwanted cluster sizes.

High ion dose is needed to realize the nano-level smoothing and etching of hard materials using cluster ion beam. Large current is needed to increase the productivity of processing. In order to get the large current cluster ion beam, the cluster generator, ionizer and ion extraction has been studied
