  The Arcminute MicroKelvin Imager (AMI) is an instrument currently under
construction in Cambridge designed to produce a survey of galaxy clusters via
the Sunyaev-Zel'dovich effect. It consists of two interferometric arrays, both
operating at 12-18 GHz; one of ten 3.7-m antennas to provide good temperature
sensitivity to arcminute-scale structures, and one of eight 13-m antennas (the
present Ryle Telescope) to provide flux sensitivity for removing contaminating
radio sources. The telescope is due to be observing by 2003, and will produce a
public survey of galaxy clusters, as well as being available to guest
observers.
