CLOVER - A new instrument for measuring the B-mode polarization of the CMB
A. C. Taylor, A. Challinor, D. Goldie +11
We describe the design and expected performance of Clover, a new instrument designed to measure the B-mode polarization of the cosmic microwave background. The proposed instrument…
Waveguide-to-planar circuit transition for millimetre-wave detectors
G. Yassin, P. K. Grimes, O. G. King +1
We present a novel design of a waveguide to microstrip or coplanar waveguide transition using a unilateral finline taper. The transition from the unilateral finline mode to the TEM…
Detecting the B-mode Polarisation of the CMB with Clover
C. E. North, B. R. Johnson, P. A. R. Ade +41
We describe the objectives, design and predicted performance of Clover, which is a ground-based experiment to measure the faint ``B-mode'' polarisation pattern in the cosmic microw…
Development of a NbN Deposition Process for Superconducting Quantum Sensors
D. M. Glowacka, D. J. Goldie, S. Withington +3
We have carried out a detailed programme to explore the superconducting characteristics of reactive DC-magnetron sputtered NbN. The basic principle is to ignite a plasma using argo…
HARP/ACSIS: A submillimetre spectral imaging system on the James Clerk Maxwell Telescope
J. V. Buckle, R. E. Hills, H. Smith +35
This paper describes a new Heterodyne Array Receiver Programme (HARP) and Auto-Correlation Spectral Imaging System (ACSIS) that have recently been installed and commissioned on the…
A blind detection of a large, complex, Sunyaev--Zel'dovich structure
AMI Consortium, :, T. W. Shimwell +58
We present an interesting Sunyaev-Zel'dovich (SZ) detection in the first of the Arcminute Microkelvin Imager (AMI) 'blind', degree-square fields to have been observed down to our t…
Development of a NbN Deposition Process for Superconducting Quantum Sensors
D. M. Glowacka, D. J. Goldie, S. Withington +2
We have carried out a detailed programme to explore the superconducting characteristics of reactive DC-magnetron sputtered NbN. The basic principle is to ignite a plasma using argo…
The Arcminute Microkelvin Imager
AMI Consortium, :, J. T. L. Zwart +57
The Arcminute Microkelvin Imager is a pair of interferometer arrays operating with six frequency channels spanning 13.9-18.2 GHz, with very high sensitivity to angular scales 30''-…
Compact broadband planar orthomode transducer
P. K. Grimes, O. G. King, G. Yassin +1
We present the design and test results of a compact C-band orthomode transducer which comprises four rectangular probes orthogonally arranged in a circular waveguide, designed to w…
High-significance Sunyaev-Zel'dovich measurement: Abell 1914 seen with the Arcminute Microkelvin Imager
AMI Collaboration, R. Barker, P. Biddulph +47
We report the first detection of a Sunyaev-Zel'dovich (S-Z) decrement with the Arcminute Microkelvin Imager (AMI). We have made commissioning observations towards the cluster A1914…
