Query: Longitudinal phase-space matching between radio-frequency systems with
  different harmonic numbers and accelerating voltages   We describe a simple mechanism to transform bunches with matched longitudinal
phase-space distributions from one RF system to a matched distribution of a
second RF system operating on a different harmonic and with a different
accelerating voltage. The process is reversible and the longitudinal emittance
is preserved. Simple equations that characterize the procedure are given and
applications are discussed. In particular this method can be used to rapidly
shorten the bunch length in proton rings.
