500 microkelvin nanoelectronics

The Arcminute Microkelvin Imager

The Arcminute Microkelvin Imager is a dual array interferometer designed specifically to survey for galaxy clusters through detecting their Sunyaev-Zel’dovich signatures on the microwave background. Construction of the Small Array is now complete and commissioning observations have mapped several clusters. The Large Array is required to remove the effects of confusing radio sources and will all...

Method for cooling nanostructures to microkelvin temperatures.

We propose a new scheme aimed at cooling nanostructures to microkelvin temperature based on the well established technique of adiabatic nuclear demagnetization: we attach each device measurement lead to an individual nuclear refrigerator, allowing efficient thermal contact to a microkelvin bath. On a prototype consisting of a parallel network of nuclear refrigerators, temperatures of ∼1 mK simu...

SZ surveys with the Arcminute MicroKelvin Imager

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 3.7m antennas to provide good temperature sensitivity to arcminute-scale structures, and one of eight 13-m antennas (the present Ryle...

Introduction to NanoElectronics

Prospects of Silicon Nanoelectronics

Silicon technology and nanoelectronics are two important components which will shape the future of the IC industry. This paper discusses their mutual interaction, i.e. the contribution that nanotechnology may o er to the evolution of MOS processing, as well as the role that silicon technology could play in the projected development of nanoelectronic
