Abstract
Using the array of seven 0.6m antennas in Hawaii, we have conducted short observations on several galaxy clusters through the Sunyaev-Zeldovich effect at 3mm wavelength in 2007. The observations were done with a resolution of 6', and we have chosen the low redshift (z=0.09-0.32) massive clusters to optimize detection. Major contamination to the data comes from instrumental offset and ground pickup. We will demonstrate the results based on a simple on source - off source switching observing scheme. In addition, the performance of a wideband analog 4-lag correlator was also investigated.
