      abstract     = {The reflectometry diagnostics for DEMO is envisaged to
                      provide the radial edge density at several poloidal angles
                      and data for the feedback control for plasma position and
                      shape. The primary integration approach for reflectometry in
                      DEMO involves the incorporation of several groups of
                      antennas and waveguides into a diagnostics slim cassette
                      (DSC), a full poloidal sector to be integrated with the
                      water-cooled lithium lead (WCLL) breeding blanket. As the
                      front-end components of the DSC will be directly exposed to
                      the plasma, an effective cooling system is required. In this
                      work, the temperature distributions of a DSC segment were
                      estimated with a coupled steady-state thermal analysis
                      performed with ANSYS Mechanical and ANSYS CFX, using the
                      system-coupling module of ANSYS Workbench. The results,
                      which also involved the computation of nuclear heat loads
                      with MCNP6, indicate that the proposed cooling system design
                      will lower the operation temperatures by more than 300 °C
                      when compared to previous designs. However, there will still
                      be hotspots in some components, with temperatures above the
                      limit of 550 °C for EUROFER under neutron irradiation.},
