Measure the amplitude of the CMB gravitational lensing, and therefore probe the mass power spectrum at 1Mpc scales at z~1-2. Find galaxy clusters at z<1 through SZ effect. Detect signature of reonization at z~15 through Vishniac effect. Find all extragalactic mm-wave point sources in 100( o ) 2 to a sensitivity of 1mJy. = 145, 225 & 265 GHz.
