Show affiliationsIt is shown that a particle detector coupled to the derivative of a scalar quantum field can be viewed as a bona fide 'particle detector'. The response of such a detector is compared with that of a linearly coupled monopole (DeWitt) detector when both are placed in each of three situations; an isotropic particle bath, in Rindler space, and in Schwarzschild space. From their responses it is shown that there is a fundamental difference in how these two detectors behave. As a result, the use of particle detectors to support the close links between quantum field theory in non-Minkowskian spaces and thermal physics is shown to be in need of deeper consideration as is the general role of particle detectors in this theory.
