Interferometric observations of the Sunyaev-Zel ’ dovich Effect ( SZE ) toward clusters of galaxies provide sensitive cosmological probes .
We present results from 1 cm observations ( at BIMA and OVRO ) of a large , intermediate redshift cluster sample .
In addition , we describe a proposed , higher sensitivity array which will enable us to survey large portions of the sky .
Simulated observations indicate that we will be able to survey one square degree of sky per month to sufficient depth that we will detect all galaxy clusters more massive than 2 \times 10 ^ { 14 } h ^ { -1 } _ { 50 } M _ { \odot } , regardless of their redshift .
We describe the cluster yield and resulting cosmological constraints from such a survey .
