Pure copper RFQ cavity in the main hall of the SPIRAL 2 LINAC

Pure copper RFQ (Radio Frequency Quadrupole) cavity in the main hall of the SPIRAL 2 LINAC (LINear ACcelerator). This structure, located at the ion source output, constitutes the injector of SPIRAL 2. Its role is to group the particles in packets (88 million packets per second) while starting to accelerate them for injection into the LINAC. SPIRAL 2 (2nd generation linear radioactive ion production system), installed at the Large National Heavy Ion Accelerator (GANIL), in Caen. SPIRAL 2 connects the LINAC to laboratories dedicated to the exploration of the atomic nucleus. The SPIRAL 2 LINAC delivers light and heavy ion beams at extremely high intensities, more than 10 times greater than those available at GANIL. It enables both light and heavy exotic nuclei to be generated, as in a nuclear reaction. Located more than 9 m underground, SPIRAL 2 is dedicated to nuclear physics and develops applications for different areas of activity including nuclear medicine, energy, aerospace etc.
