  We present the angular power spectrum of the CMB component extracted with
FastICA from the Background Emission Anisotropy Scanning Telescope (BEAST)
data. BEAST is a 2.2 meter off-axis telescope with a focal plane comprising 8
elements at Q (38-45 GHz) and Ka (26-36 GHz) bands. It operates from the UC
White Mountain Research Station at an altitude of 3800 meters. The BEAST CMB
angular power spectrum has been already calculated by O'Dwyer et.al. using only
the Q band data. With two input channels FastICA returns two possible
independent components. We found that one of these two has an unphysical
spectral behaviour while the other is a reasonable CMB component. After a
detailed calibration procedure based on Monte-Carlo (MC) simulations we
extracted the angular power spectrum for the identified CMB component and found
a very good agreement with the already published BEAST CMB angular power
spectrum and with the WMAP data.
