  One of the primary reasons behind the difficulty in observing the Unruh
effect is that for achievable acceleration scales the finite temperature
effects are significant only for the low frequency modes of the field. Since
the density of field modes falls for small frequencies in free space, the field
modes which are relevant for the thermal effects would be less in number to
make an observably significant effect. In this work, we investigate the
response of a Unruh-DeWitt detector coupled to a massless scalar field which is
confined in a long cylindrical cavity. The density of field modes inside such a
cavity shows a {\it resonance structure} i.e. it rises abruptly for some
specific cavity configurations. We show that an accelerating detector inside
the cavity exhibits a non-trivial excitation and de-excitation rates for {\it
small} accelerations around such resonance points. If the cavity parameters are
adjusted to lie in a neighborhood of such resonance points, the (small)
acceleration-induced emission rate can be made much larger than the already
observable inertial emission rate. We comment on the possibilities of employing
this detector-field-cavity system in the experimental realization of Unruh
effect, and argue that the necessity of extremely high acceleration can be
traded off in favor of precision in cavity manufacturing for realizing
non-inertial field theoretic effects in laboratory settings.
