The Sunyaev-Zel'dovich effect is a powerful probe useful to investigate both the properties of galaxy clusters and cosmological parameters. We are developing low-noise SIS mixer- based receivers for continuum observations at 90 GHz. By using these receivers at the SRT we can investigate galaxy clusters at high redshift, where the typical core \textit{radii} are comparable to the angular resolution of the telescope at 100 GHz. These sources are largely unexplored but their interest will be increasing in the near future due to X-ray observations from satellites.

Abstract
The Sunyaev-Zel'dovich effect is a powerful probe useful to investigate both the properties of galaxy clusters and cosmological parameters. We are developing low-noise SIS mixer- based receivers for continuum observations at 90 GHz. By using these receivers at the SRT we can investigate galaxy clusters at high redshift, where the typical core \textit{radii} are comparable to the angular resolution of the telescope at 100 GHz. These sources are largely unexplored but their interest will be increasing in the near future due to X-ray observations from satellites.
