I am a SUPA Advanced Fellow working at the Royal Observatory, Edinburgh and in the Institute for Gravitational Research and the Particle Physics Experiment group in Glasgow. My particular area of SUPA is the TEOPS initiative. I am also involved in ATC Innovations.

New

A note on why I don't think the concept of static thermal conductance - popular in bolometer analysis - is very useful.

Due to popular request, here is my LTD13 paper on a low temperature thermal conductivity database.

A thermal conductivity calculator for pure copper is now available here.

Some recent talks:

SPIRE - the state-of-the-art in semiconductor bolometers for astronomy

A list of other talks is here.

Some recent papers:

Thermal design and performance of the SCUBA-2 instrument 1-K and mK systems
Accepted by Cryogenics and available on-line.

Detectors for sub-millimetre continuum astronomy.
Nuclear Instruments and Methods in Physics Research Section A., 604 (1-2):30-33, 2009.

For other papers, see my publication list.

Other things:

Thermal conductivity calculators, for aluminium and copper.
These calculators can provide a table of thermal conductivity values between 1 and 300 K for pure copper and aluminium of arbitrary purity, and for their alloys. The purity can be specified by a conductivity value at 4 K, a residual resistivity or RRR value, or (for aluminium alloys) by the alloy type.

Part of my research work involves efforts to improve cryogenic instrumentation.

An introduction to semiconductor bolometer modelling - a short document on modelling cryogenic semiconductor bolometers, with the emphasis on how simple it actually is

The LTUK web site; information about cryogenics, particularly in the UK.
