| Summary: | The QUIJOTE Experiment has been built to study the polarization of the Cosmic Microwave Background (CMB). The study of the CMB provides one of the most powerful tools in modern cosmology. In particular, CMB polarization offers a new window onto the inflationary phase of the Universe, some 10-35 seconds after the Big Bang. Measurement of the CMB spectrum to an accuracy that will reveal interesting science (micro-kelvin variations) is particularly difficult because there are many systematics that lead to effects higher than this level. There are several instruments that have been designed for CMB spectral measurement (FIRAS-COBE, ARCADE, PIXIE). The present plan is to extend the goals of QUIJOTE by building a new and unique microwave spectrometer in the frequency range 10-20 GHz, with the aim of characterizing the spectral signals associated with the reionization epoch and dark ages in the Universe. This document describes the first component for the Tenerife Microwave Spectrometer (TMS), an ultra-wideband bandpass filter (BPF). A filter prototype covering the 10-20 GHz band has been successfully designed, manufactured, and measured in the laboratory to compare results and simulations. |
