  We analyse the entanglement and the non-locality of a (1+1)-dimensional
massless Dirac field confined to a cavity on a worldtube that consists of
inertial and uniformly accelerated segments, for small accelerations but
arbitrarily long travel times. The correlations between the accelerated field
modes and the modes in an inertial reference cavity are periodic in the
durations of the individual trajectory segments, and degradation of the
correlations can be entirely avoided by fine-tuning the individual or relative
durations of the segments. Analytic results for selected trajectories are
presented. Differences from the corresponding bosonic correlations are
identified and extensions to massive fermions are discussed.
