  We consider an array of non-locally coupled oscillators on a ring, which for
equally spaced units possesses a Kuramoto-Battogtokh chimera regime and a
synchronous state. We demonstrate that disorder in oscillators positions leads
to a transition from the synchronous to the chimera state. For a static
(quenched) disorder we find that the probability of synchrony survival changes,
in dependence on the number of particles, from nearly zero at small populations
to one in the thermodynamic limit. Furthermore, we demonstrate how the
synchrony gets destroyed for randomly (ballistically or diffusively) moving
oscillators. We show that, depending on the number of oscillators, there are
different scalings of the transition time with this number and the velocity of
the units.
