than even the Large Hadron Collider (LHC) (first collisions produced in 2010) or perhaps even the Linear Collider Collaboration (LCC) experiments (design incomplete as of 2019.) European Neutrino Group CERN did a design study a few years ago, before effort moved on to the LHC. Activities in Europe continue with meetings and involvement in international experiments and collaborations. Japanese design This is based on an unusual type of accelerator called an Fixed Field Alternating Gradient (FFAG) that combines elements from the cyclotrons of the 1950s with modern automated magnet design processes, and new magnetic alloy radiofrequency accelerating gaps. The main advantage of these is that the magnetic fields are fixed and do not have to be synchronised to the beam in any way, yet the beam naturally moves into regions of higher field as its energy increases, allowing for very rapid acceleration without the difficulties found in very rapid-cycling synchrotrons.
