    We show, in complete accord with the usual Rindler picture, that detectors with constant acceleration aa in de Sitter (dS) and Anti de Sitter (AdS) spaces with cosmological constants Λ\Lambda measure temperatures 2πT=(Λ/3+a2)1/2≡a52\pi T=(\Lambda/3+a^{2})^{1/2}\equiv a_{5}, the detector "5-acceleration" in the embedding flat 5-space. For dS, this recovers a known result; in AdS, where Λ\Lambda is negative, the temperature is well defined down to the critical value a5=0a_{5}=0, again in accord with the underlying kinematics. The existence of a thermal spectrum is also demonstrated for a variety of candidate wave functions in AdS backgrounds.Comment: Latex +2 Fi
