  abstract     = {{The Acculinna-2 radioactive beam separator was designed and built between 2012 and 2014, then installed and tested by Sigmaphi in 2015 and in full operation since 2016 at the Flerov laboratory of JINR in Dubna. In order to achieve efficient separation of neutron-deficient species, an RF kicker was foreseen since the beginning of the project but was put on hold for many years. In 2016 Sigmaphi got a contract to study, build, install and test an RF kicker with a variable frequency ranging between 15 and 21 MHz and capable of producing 15kV/cm transverse electric fields in a 10 cm gap over a 1m long distance.# The presentation first recalls the rationale of an RF-kicker to separate neutron-deficient species. It then goes through the different steps of the study, initial choice of the cavity structure, first dimensioning from analytical formulas, finite elements computations and tuning methods envisioned, down to a final preliminary design.# A 1/10 scaled mock-up of this final shape was built and tested as a check before building the full-size cavity. The NTG company was then contracted to perform, in a joint collaboration with Sigmaphi, the final study, detailed design, construction and factory testing of the real cavity. The presentation highlights the fabrication and tests of both mock-up and real size cavities through a series of pictures.# The complete RF-kicker, with its power supply, control and pumping systems was installed on the Acculinna-2 beamline in June 2019. Because the U400M cyclotron was due to shut down by mid-2020, the Acculinna-2 team decided to use the separator to accumulate as much data as possible, to be processed during the 2 years closing time. A 1-week time window for kicker testing was only available in February 2020, a short but sufficient time lapse to successfully drive the cavity at full power and test it over a wide frequency range. Unfortunately, because of cyclotron closure, no beam tests have been performed so far. The latest availabl}},
