The energy-momentum tensor for a massless conformally coupled scalar field in the region between two curved surface moving by uniform proper accelerations in static de Sitter spacetime is investigated. We assume that the scalar field satisfies the Robin boundary condition on the surfaces. Static de Sitter space is conformally related to the Rindler space, as a result we can obtain vacuum expectation values of energy-momentum tensor for conformally invariant field in static de Sitter space from the corresponding Rindler counterpart by the conformal transformation.
