According to Jones, the challenge is finding a way to suppress wake fields sufficiently while still maintaining a high acceleration field to perform particle collisions. "Wake fields have been carefully controlled and suppressed in the Large Hadron Collider (LHC) at CERN. However, physicists are now looking at what comes after the LHC" Prof Jones said. "An electron-positron collider is the natural successor to the LHC and it turns out the wake fields are much more severe in these linear collider machines," he added. Full Article at Newstrack India
