Comment on “Instability studies at the CERN Proton Synchrotron during transition crossing”

Abstract

Article and the Authors, the long-standing qualification of the PS instability as the transverse mode-coupling instability, or TMCI, is not mentioned, while a model of the beam breakup (BBU) is discussed. Do the observations and modeling of the Article refute the longstanding idea that the PS instability is the TMCI?
