A charge exchange device, typically used in an ion beam accelerator, includes a charge exchange tube defining a charge exchange chamber and beam ports for allowing an ion beam to enter and exit the charge exchange tube, a containment tube mounted external to the charge exchange tube, the containment tube having an entrance port for a charge exchange material, and at least one intermediate tube mounted between the charge exchange tube and the containment tube. The charge exchange tube and the at least one intermediate tube have at least one set of flow ports that are aligned on opposite sides of the charge exchange chamber to permit columnated flow of the charge exchange material into and through the charge exchange chamber. Leakage of the charge exchange material through the beam ports is reduced in comparison with prior art charge exchange devices.
