Abstract: Abstract: We report an absorber-coupled superconducting Transition Edge Sensor (TES) bolometric polarimeter for measuring Cosmic Microwave Background (CMB) B-mode polarization. The polarimeter consists of a dipole-like PdAu absorber and a Mo/Au bi-layer TES on a suspended silicon nitride rectangle. Its design, fabrication, thermal properties, and optical performance are presented. [Copyright &y& Elsevier]
