  Traditionally the physics of the Unruh effect, i.e. the q.f.t. in the wedges
$W_R$ or $W_L$ in Minkowski space is related to the physics in the Rindler Fock
space, which is a proplematical strategy. In a careful analysis we show that
the correct dual q.f.t. lives rather in the thermal Rindler Hilbert space and
turns out to be unitarily equivalent to the corresponding Minkowski space
theory in contrast to the Rindler Fock space theory. We show in particular that
in thermal Rindler Hilbert space a new sort of objects occurs, viz.,
quasi-particle/hole creation/annihilation operators of thermal Rindler
quasi-particles and holes, which do not have a pendant in Rindler Fock space.
The ordinary Rindler particle operators are certain temperature dependent
superpositions of these more fundamental operators. These new objects play a
crucial role in this duality and via the unitary equivalence do have their
counterparts in Minkowski q.f.t.
