Gethin Robson

Research student,


I began my PhD here at Cardiff in October 2020 after completing my integrated Master’s degree at Lancaster University with my fourth year thesis on the realisation of a superconductor-insulator-normal metal junction as a high-speed thermometer.

Now, I work within the Instrumentation group with Dr. Simon Doyle on the development of superconducting filter-banks and detectors known as kinetic inductance detectors.

The goal of my research is to demonstrate a large format, highly sensitive detector technology suitable for photometry, polarimetry and spectroscopy in millimetre and sub-millimetre astronomy.


Research interests

I am interested in the use of superconducting micro-resonators embedded in microwave circuits to create highly sensitive detectors for millimetre and submillimetre signals, these devices are commonly known as kinetic inductance detectors.

Currently, I am working on a project to install a superconducting on-chip millimetre spectrometer on the South Pole Telescope (SPT) as a technology demonstration to pave the way for future large format line intensity mapping experiments. My involvement in this project is the development of the device and detector architecture.
