This paper presents the analysis, design, and characterization of the thirty gigahertz instrument receiver developed for the Q-U-I Joint Tenerife experiment. The receiver is aimed to obtain polarization data of the cosmic microwave background radiation from the sky, obtaining the Q, U, and I Stokes parameters of the incoming signal simultaneously. A comprehensive analysis of the theory behind the proposed receiver is presented for a linearly polarized input signal, and the functionality tests have demonstrated adequate results in terms of Stokes parameters, which validate the concept of the receiver based on electronic phase switching.

“…[1], [2], [3], [4]). The present plan is to extend the goals of the QUIJOTE-CMB Experiment ( [5], [6], [7], [8]) by building a new microwave spectrometer in the frequency range [10][11][12][13][14][15][16][17][18][19][20] GHz. The measurement of the CMB spectrum to the accuracy that will reveal interesting science is particularly difficult because there are many uncertainties that lead to effects of the order of this level.…”

The QUIJOTE Experiment was developed to study the polarization in the Cosmic Microwave Background (CMB) over the frequency range of 10-50 GHz. Its first instrument, the Multi Frequency Instrument (MFI), measures in the range 10-20 GHz which coincides with one of the naturally transparent windows in the atmosphere. The Tenerife Microwave Spectrometer (TMS) has been designed to investigate the spectrum between 10-20 GHz in more detail. The MFI bands are 2 GHz wide whereas the TMS bands will be 250 MHz wide covering the complete 10-20 GHz range with one receiver chain and Fourier spectral filter bank. It is expected that the relative calibration between frequency bands will be better known than the MFI channels and that the higher resolution will provide essential information on narrow band interference and features such as ozone. The TMS will study the atmospheric spectra as well as provide key information on the viability of ground-based absolute spectral measurements. Here the novel Fourier transform spectrometer design is described showing its suitability to wide band measurement and √ N advantage over the usual scanning techniques.

“…The analysis of the Cosmic Microwave Background (CMB) polarization lies in the focus of current CMB missions such as Planck, as well as future missions [1][2][3][4][5][6][7][8]. The main scientific goal is to detect primordial gravitational waves in the B-mode of the polarized CMB signal.…”

Methods for pixel domain correction of EB leakage

In observation of the cosmic microwave background (CMB) polarization, "EB leakage" refers to the artificial B-mode signal coming from the leakage of E-mode signal when part of the sky is unavailable or excluded. Correction of such leakage is one of the preconditions for detecting primordial gravitational waves via the CMB B-mode signal. In this work, we design two independent methods for correcting the EB leakage directly in the pixel domain using standard definitions of the Eand B-modes. The two methods give consistent results, and both are fast and easy to implement. Tests on a CMB simulation containing zero initial B-mode show an efficient suppression of the EB leakage. When combined with the MASTER method to reconstruct the full-sky B-mode spectrum in simulations with a relatively simple mask, the error from EB-leakage is suppressed further by more than one order of magnitude at the recombination bump, and up to three orders of magnitude at higher multipoles, compared to a "pure" MASTER scheme under the same conditions. Meanwhile, although the final power spectrum estimation benefits from apodization, the pixel domain correction itself is done without apodization, and thus the methods offer more freedom in choosing an apodization based on specific requirements.
