APPARATUS FOR PRE-ACCELERATION OF ION BEAMS USED IN A HEAVY ION BEAM APPLICATION SYSTEM.

摘要

An apparatus for ion beam pre-acceleration and optimized adaptation of the beam parameters, suitable for use in heavy ion beam application systems, comprising: - a quadrupole radiofrequency accelerator (RFQ) having two pairs of mini-pallets (EL ) supported by a plurality of alternating rods (ST) that accelerate the ions, wherein said radiofrequency quadrupole (RFQ) has an opening that increases towards the end of its structure and where said radiofrequency quadrupole (RFQ) additionally has a phase synchronous that increases towards 0 degrees towards the end of the structure, - a complete interdeposition adaptation section for adaptation of the parameters of the ion beams that come from the quadrupole radiofrequency accelerator (RFQ) to the parameters required by a linear tube accelerator subsequent drift (DTL), - two regrouping drift tubes positioned at the output of the radiofrequency (RF) quadrupole Q), characterized in that the regrouper drift tubes are integrated in the radiofrequency quadrupole (RFQ) tank.
