Abstract

We present a measurement of the angular spectrum of the cosmic microwave background from l = 26 to 225 from the 30 and 40 GHz channels of the MAT/TOCO experiment based on two seasons of observations. At comparable frequencies, the data extend to a lower l than the recent Very Small Array and DASI results. After accounting for known foreground emission in a self-consistent analysis, a rise from the Sachs-Wolfe plateau to a peak of δT_l ≈ 80 μK near l ≈ 200 is observed.
