Abstract :
The transport and cooling of noble gas singly charged ion beams by means of a Radio Frequency Quadrupole Cooler Buncher have been studied at the LIMBE low-energy beam line of the GANIL facility. Ions as light as 4He+ have been cooled and stored before their extraction in bunches using H2 as buffer gas. Bunches characteristics have been studied as a function of the parameters of the device. Sizeable transmissions of up to 10% have been obtained. A detailed study of the lifetime of ions inside the buncher has been performed giving an estimate of the charge exchange cross-section. Results of a microscopic Monte Carlo transport code show reasonable agreement with experimental data.
