Description Novel dry cryogenics to cool ground-based detector systems to sub-K temperatures. Novel horns and OMTs and novel optics.
Exploitation Route Our design is state-of-the-art for future CMB B-modes experiments.
Sectors Education

Electronics

 
Description The CLOVER project was canceled by the funding agency before being completed. We managed to develop the hardware and software of our responsibility. A) design, construction and testing of a Pulse Tube Cooler based large cryostat for cooling to 100 mK an array of TES bolometers. B) design, construction and testing of horns and OMTs to couple the sky radiation to the bolometer array.
