Thirty-GHz Instrument


    The second QUIJOTE Instrument (or 30 GHz Instrument) will be mainly devoted to primordial B-mode science. TGI will be fitted with 31 polarimeters working in the range of 26-36GHz. The current design of a single polarimeter for the TGI is presented in the figure below. It includes a fixed polarizer and 90 deg and 180 deg phase switches to generate four polarisation states to minimize the different
    systematics in the receiver.
