Expected performance of AMiBA with the initial configuration (seven 60cm dishes, close-packed) after 1 month of observations, as compared with other high-l CMB experiments such as ACBAR (2002) and CBI (2004). Also shown are the WMAP best-fitting curve of

In addition to studies of high redshift clusters, the AMiBA will also measure the power spectrum of the CMB on smaller sizescales than have been attained before. Calculations show that even with the 60 cm reflectors, the previously measured CMB power spectrum can be detected within a reasonable integration time. The ability to sample smaller structures, will allow us to study the potential presence of the secondary Sunyaev Zel'dovich effect on the CMB power spectrum. Figure 7 shows the potentials of AMiBA versus other instruments.
