Holzapfel, M Lueker, M Newcomb, D Woolsey, C. L. Kuo, A. E. Lange, M. C. Runyan, J Ruhle, J. H. Goldstein, E TorbetArcminute Cosmology Bolometer Array Receiver (Acbar) is a multifrequency millimeter-wave receiver optimized for observations of the Cosmic Microwave Background (CMB) and the Sunyaev-Zel'dovich (SZ) effect in clusters of galaxies. Acbar was installed on the 2.1 m Viper telescope at the South Pole in January 2001 and the results presented here incorporate data through July 2002. The power spectrum of the CMB at 150 GHz over the range l=150 - 3000 measured by Acbar is presented along with estimates for the values of the cosmological parameters within the context of ?CDM models. The inclusion of O_? greatly improves the fit to the power spectrum. Three-frequency images of the SZ decrement/increment are also presented for the galaxy cluster 1E0657-67.
