The Physics of the Accelerating Universe (PAU) is a new project whose main goal is to measure the baryon acoustic oscillations (BAO) in the galaxy distribution to characterize dark energy. For this purpose, it will build a new large field of view camera (the PAU Camera) to carry out a wide area imaging survey with narrow band filters spanning the optical wavelength range. The PAU Camera is at an early stage of design. Currently, it is designed to have a focal plane field of view of approximately 45cm in diameter, that will be densely populated by state of the art CCDs. The PAU Camera will use a new set of approximately 45 narrow band filters ranging from ~4200 to ~8700 angstroms with two additional wide band filters at the blue and red ends of the spectrum. The camera will operate in drift-scan mode. The PAU Camera is expected to be mounted either in a purposely designed 2.5m class wide field telescope or in an existing telescope that could be adapted to deliver a wide field.
