The Q/U Imaging ExperimenT (QUIET), a ground-based experiment located in the Atacama Desert in Chile, measures the polarization of the Cosmic Microwave Background (CMB). In Phase I, it measures the CMB polarization at angular scales of 25 < l < 1000 using radiometer arrays in the Q (44 GHz) and W (95 GHz) frequency bands. In the period of October of 2008 to December of 2010, more than 7500 hours of CMB data were collected, first with the 19-element Q-band receiver and then with the 90-element W-band receiver. The Q- and W- band receivers each observed the same 4 low-foreground fields that covered 1000 square degrees.
Here, we present the initial results of the Q-band receiver from Phase I, including the EE and BB power spectra in the multipole range 26 < l < 475, and our resulting tensor-to-scalar ratio r. Before examining the resulting power spectra, the data were studied with two independent analysis pipelines, each with its own large suite of null tests.
