RF Characterization of the New TOTEM Roman Pot

The aim of the present work is the optimization of the Roman Pot (RP) design to minimize the beam-coupling impedance, in particular when the RP is inserted very close to the beam. Indeed, in the first period of running of the LHC a rise in temperature due to RF has been observed both in the ALFA and TOTEM RP. After the LS1 the LHC beam current will increase and the equipments that can interact with the beam need to be optimized; moreover, new detectors for the TOTEM upgrade program require a longer longitudinal dimension of the RP. A new RP design has been proposed and developed by the TOTEM collaboration; this work will describe the studies done to optimize the beam-coupling impedance of the new design.
