We consider inertial and accelerated Unruh-DeWitt detectors moving in
a background thermal bath and calculate their excitation rate. It is s
hown that for fast moving detectors such a thermal bath does not affec
t substantially the excitation probability. Our results are discussed
in connection with a possible proposal of testing the Unruh effect in
high energy particle accelerators.
