abstract = {The plasma diagnostic and control $(D\&C)$ system for a
future tokamak demonstration fusion reactor (DEMO) will have
to provide reliable operation near technical and physics
limits, while its front-end components will be subject to
strong adverse effects within the nuclear and high
temperature plasma environment. The ongoing developments for
the ITER $D\&C$ system represent an important starting point
for progressing towards DEMO. Requirements for detailed
exploration of physics are however pushing the ITER
diagnostic design towards using sophisticated methods and
aiming for large spatial coverage and high signal
intensities, so that many front-end components have to be
mounted in forward positions. In many cases this results in
a rapid aging of diagnostic components, so that additional
measures like protection shutters, plasma based mirror
cleaning or modular approaches for frequent maintenance and
exchange are being developed.Under the even stronger
fluences of plasma particles, neutron/gamma and radiation
loads on DEMO, durable and reliable signals for plasma
control can only be obtained by selecting diagnostic methods
with regard to their robustness, and retracting vulnerable
front-end components into protected locations. Based on this
approach, an initial DEMO $D\&C$ concept is presented, which
covers all major control issues by signals to be derived
from at least two different diagnostic methods (risk
mitigation).},
