      abstract     = {Microwave reflectometry systems are currently considered as
                      a possible solution for plasma position and control, in
                      DEMO. The primary integration approach for this diagnostic
                      involves the incorporation of several groups of antennas and
                      waveguides into a diagnostics slim cassette (DSC), a full
                      20–25 cm thick poloidal sector dedicated to diagnostics.
                      Since the passive front-end components of the reflectometry
                      system (antennas and WGs) will be directly exposed to the
                      plasma, an effective cooling system is required to keep the
                      operating temperatures below the limits established for the
                      DSC materials under neutron irradiation. Furthermore, the
                      mechanical stresses experienced by the DSC should not
                      jeopardize its structural integrity. In this work, the
                      temperature distributions of a DSC segment with an updated
                      cooling system design were estimated with a coupled
                      steady-state thermal analysis performed with ANSYS
                      Mechanical and ANSYS CFX, using the system-coupling module
                      of ANSYS Workbench. It was found that the maximum
                      temperature obtained in the DSC could be below the limits if
                      the antennas are made of tungsten. These results were used
                      as input in structural analysis, which has shown that the
                      structure of the designed DSC fulfils the level-A
                      requirements of RCC-MR for Immediate Plastic Collapse (IPC),
                      Immediate Plastic Instability (IPI), and Immediate Plastic
                      Flow Localization (IPFL).},
