Overview
My research is based on developing the next generation of astronomical instrumentation for use in the sub-millimetre and far infrared regimes. I concentrate on the development of hyper-sensitive, high-pixel count detector arrays using the LEKID architecture and also the design and commissioning of the sub-Kelvin cryogenic cooling platforms that are required for these detectors.
I am the cryogenic development lead for the MUSCAT instrument on the Large Millimeter Telescope in Mexico. The bespoke cooling system of MUSCAT, developed in close partnership with commercial partners, utilises novel continuously operating helium sorption fridges combined with a miniature dilution fridge to provide a detector-stage temperature of 100 mK (-273.05°C, 0.1°C above absolute zero). A unique feature of this system is that, compared to similar systems, MUSCAT uses very little helium-3 which is scarce and expensive.
The detectors I develop have applications in studying the light from other galaxies, helping to understand for stars form and study the cosmic microwave background (a remnant of the Big Bang).
