We present information about the design and fabrication of 90 GHz Transition Edge Sensor (TES) detectors deployed in the SPTpol camera for investigation of the cosmic microwave background (CMB) polarization signal. The 90 GHz portion of the camera consists of 180 individual feedhorn modules with dua...
