The focus of this activity is in the overview of the different technologies and implementation of the most promising one. In the case of the KIDs detectors, the focus would be in the design of the dual polarization wide band antenna, in combination with the Anti Reflection (AR) coating, where on-chip superconducting circuits are used to spectroscopically detect the radiated power in each independent polarization. In the case of bolometers, the design would benefit from the dual polarized bolometers developed for the B-BOP instrument of SPICA. The focus would be in the design of the Fabry-Perot filter bank, paying attention to the filtering capability, losses of the superstrate and frequency coverage. In the scope of this activity, a focal plane array containing 10 spatial pixels would be envisaged. Each spatial pixel would consist off an AR coated lens with underneath the rest of the detection chain including an antenna, filters and KIDs. In the case of bolometers, the selectivity of 10 different frequencies shall be demonstrated. In order to allow the Focal plane filling, the whole detector chain shall be compact enough to fit under the lens/superstrate. Considering the current CMB channels with typical 20% bandwidth, 4-5 spectral channels could be connected to the feed of a single 1:2 bandwidth lens-antenna. This would allow the implementation of the full FPA with only three kinds of pixels. This would mean a simplification of the FPA by a factor of 2 with respect to the typically considered FPA. Task list: – Requirements consolidation and architecture trade-off – Preliminary design and critical breadboarding – Detailed design and analysis – Manufacturing and integration – Testing – Conclusions and recommendations.
