A General Overview on the 2017 ICFA Mini-Workshop on Impedances and Beam Instabilities in Particle Accelerators

The ICFA mini-Workshop on impedances and beam instabilities in particle accelerators, which took place in Benevento (Italy) from 18 to 22 September 2017, was intended to continue the tradition of dedicated conferences on the subject of beam coupling Impedances in particle accelerators, initiated with the 2014 ICFA mini-Workshop on “Electromagnetic Wake Fields and Impedances in Particle Accelerators” held in Erice (organized by Vittorio Vaccaro, Maria Rosaria Masullo and Elias Métral). The aim of the event was therefore to provide an up-to-date review of the subject, while widening its scope to include recent advances on beam instabilities and different instability sources. The workshop was hosted by the University of Sannio at Benevento, under the auspices of the Italian Institute for Nuclear Physics (INFN), the Italian Physical Society (SIF) and CERN - and with the sponsorship of the European network ARIES, as well as the running projects for LHC Injectors Upgrade (LIU), Collimation and High Luminosity LHC (HL-LHC).
