PRESS RELEASE BY UNIVERSITY OF SHEFFIELD
Dilution refrigerator which will support research into quantum technology unveiled
A dilution refrigerator which can provide an ultra-low temperature environment close to zero to support research into dark matter has been unveiled in the Department of Physics, University of Sheffield.
Manufactured by Oxford Instruments, the apparatus will permit experiments at a temperature a hundredth of a degree centigrade above absolute zero, allowing precise measurements of nature in its quantum regime, and searches for axion dark matter.
Funded by UK Research Councils (UKRI) through the Science and Technology Facilities Council (STFC), it is the first closed cycle dilution refrigerator at the University of Sheffield.
The refrigerator will be utilised by the Quantum Sensors for the Hidden Sector collaboration, led by Professor Ed Daw, who is also the group principal investigator in Sheffield.
As well as searching for axions, the refrigerator will be used to make precise measurements of the performance and properties of quantum electronics devices such as amplifiers, power sensors, and engineered two-state quantum systems called qubits.
There will also be opportunities for PhD students and undergraduates to gain experience in ultra-low-temperature physics and the operation of dilution refrigerators, a skill highly relevant to growth areas in industry such as quantum instrumentation and quantum computing.
Professor Daw said: “It is really exciting to be starting to operate a dilution refrigerator here at Sheffield, and I anticipate many interesting and ground-breaking applications.
“There aren’t so many facilities like this in the North East, so it is also wonderful to be instrumental in some real levelling up!
“I hope what we do in our lab will be of benefit to the wider community, both at our own University, and through our collaborations with other institutions across the UK and internationally.”
March 2024
Installation of the Oxford Instruments Proteox Dilution Fridge and Magnet (6T) is complete. Staff training has gone well and the fridge has successfully cooled to base temperature.

Royal Society Summer Exhibition 2024
Congratulations to Professor Ed Laird and the team, University of Lancaster, who have been selected to exhibit at the Royal Society Summer Exhibition, 2-7 July 2024.
The origins and nature of our universe are topics which fascinate young and old. We can all look out at the stars and galaxies in the sky, and yet what we can see is only a fraction of the matter in our universe. Most of the matter in the universe is dark, meaning that it cannot be seen – or even, so far, detected, even though we apparently live within a galaxy-size cloud of it. We know it exists because we can see the effects of its gravity on the evolution of galaxies and of the entire universe, but experiments to date have failed to detect it. This is arguably the greatest challenge of 21st century physics.
Our research uses the very same quantum technologies being developed for quantum computing to build ultra-sensitive dark matter detectors. Quantum computing is a popular topic for the wider public, however our exhibit will show how those same technologies can also deliver answers to some of the most exciting pure research goals, turning a table-top experiment into a big-science observatory.
Our exhibit will use several hands-on demonstrations to provide an intuitive, accessible way to explore these difficult concepts. We are excited to create the exhibits and have plenty of experience making fundamental research accessible to the public through previous Summer Science exhibitions and elsewhere. For secondary school students, these demonstrations will help to explain some of the topics they will encounter in their studies, in some places using GCSE and A-level science topics such as gravity, resonance, and pendulums. We will also produce educational online content with links to further resources that can be used by students and teachers to explore these concepts, including information on how to recreate aspects of the exhibit.”
The Royal Society Summer Science Exhibition is one of the UK’s leading science outreach events and provides a unique opportunity for members of the public to interact with scientists and ask them questions about their work. See https://royalsociety.org/science-events-and-lectures/about-exhibitions/

QSHS Collaborator Subir Sarkar, University of Oxford, writes about the GGI Florence Workshop, Galileo Galiei Institute for Theoretical Physics:
The Galileo Galiei Institute in Florence recently organized a Workshop during 26 April to 9 June 2023 on: Axions across boundaries between Particle Physics, Astrophysics, Cosmology and forefront Detection Technologies. “The purpose of this workshop was to bring together scientists with different backgrounds and expertise to discuss open problems, recent developments and future directions in axion physics, a field that is notoriously replete with interdisciplinary connections. The aim is to foster a fruitful cross breeding between different theoretical areas, with a focus on certain open issues in axion particle physics, astrophysics and cosmology. Quantitative assessments of the axion contribution to Cold Dark Matter (CDM) involve top-notch lattice simulations of non- perturbative QCD effects, as well as of the cosmic evolution of axionic topological defects. Astrophysical observations provide strong bounds on axion properties because stellar evolution would be affected by the existence of axions and, intriguingly, some excesses in star energy losses have been reported. Cosmological scenarios in which the Peccei-Quinn symmetry is broken before inflation foresee axions imprints in the CMB, while in post-inflationary scenarios axion miniclusters, with overdensities several orders of magnitude larger than the local density of CDM, are expected to form, and a reliable assessment of their properties is of utmost importance. From the experimental side, a blossoming of potentially game-changing ideas, with an exciting crossover from experimental particle physics to materials science and cutting-edge technologies is inspiring new methods for axion searches. Novel techniques have been put forth that, besides exploiting the axion- photon coupling, aim to reveal axions via their couplings to nucleons and electrons. The interaction between the experimental and theoretical communities will foster the merging of `how to search’ with `where to search’ into optimized strategies to hunt for the axion.”
* Training week (1st week: April 26-28)
* Axion astrophysics (2nd & 3rd weeks: May 2-12)
* Axion cosmology (3rd & 4th weeks: May 8-19)
* Axions in particle physics (4th & 5th weeks: May 15-26)
* Axion experiments (5th & 6th weeks: May 22-June 1)
* Conference week (7th week: June 5-9)
There were many interesting talks by both theorists and experimentalists and vigorous discussions. From the QSHS collaboration, Ed Hardy attended Wks 2 & 3 and gave a seminar on Axion contribution from topological strings, while Subir Sarkar attended Wk 7 and gave a talk on The cosmological axion domain wall problem.
Sheffield Lead Investigator, Ed Daw, welcomed a Summer Work Experience placement to join the team for a few days to get a taste of what it is like to be a researcher in the Department of Physics & Astronomy at the University of Sheffield. Angela Warren, Project Manager, devised a programme of tasks, and together with the help of colleagues Paul Smith, Mitch Perry, and Claude Mostyn, we were able to provide them with a glimpse of our research. At the end of their week the feedback was positive: “they had had a wonderful week and thoroughly enjoyed the experience. What a fantastic opportunity for them to explore the laboratories and see the work which is being undertaken. They very much enjoyed spending their time with staff members. Conversations with their family during the evenings were so interesting and hearing the enthusiasm about what they had been doing and learning was amazing” were some of the comments.
Note: this work placement was organised through the usual official school application process.
June 2023
QSHS PhD Student Claude Mostyn returns from Seattle. Below is a summary of how they spent their time working with our US collaborator ADMX:
“I spent 80 days working with the Axion Dark Matter eXperiment (ADMX) at the Centre of Experimental Nuclear Physics and Astrophysics (CENPA) at the University of Washington, Seattle.
I largely worked on a thermal report of the radio frequency (RF) cabling in the ADMX insert, helping to decrease their heat loads as much as possible whilst maintaining low enough attenuations, and noise temepratures to maintain the signal to noise ratio, whilst pushing for lower temperatures in future runs. I then presented the results of these tests/calculations and the new RF cabling set-up made alongside Gray Rybka to the wider collaboration in a weekly meeting – I got some good feedback and enjoyed hearing the inputs and questions from the wider team based on their areas of expertise. I developed a spreadsheet to estimate conductive cable heat loads to allow future cabling changes to be quickly compared.
I also helped out with some of the day-to-day jobs at ADMX, including leak testing and cleaning valves in the dilution fridge; along with cable and component testing (including talking with companies when finding faulty cables), and measuring room-temperature, noise temperatures and gains. Getting to use the laithes, mills and various metal cutters and saws in the student machine shop was also absolutely great.
The highlight was getting to work with the group at ADMX, from fellow grad students and professors to undergrads; everybody was welcoming, friendly, and enthusiastic about the work, and it was a wonderful team. Visitors to ADMX were also very interesting to talk to and meet, including some from the Taiwanese and Korean axion experiments.
Seattle outside of CENPA was also very enjoyable; I hiked (not all the way up) Mt Rainier, and drove with some other CENPA grad students out to East Washington to see the Ancient Lakes; I also got to see some small theatre shows, with “Lydia and the Troll” at the Seattle Rep being a stand out.
Overall, it was a great experience and I am extremely grateful to the team at ADMX, and Gray Rybka in particular for having me, and I am sure we’ll meet again.”

Quantum Sensors for the Hidden Sector (QSHS) – A Summary of Our First Year!
| “Quantum Sensors for the Hidden Sector (QSHS) – A Summary of Our First Year!” In 2021 the Quantum Sensors for the Hidden Sector (QSHS) collaboration was founded in the UK. We received funding as part of the Quantum Technologies for Fundamental Physics programme to develop and demonstrate quantum devices with the potential to detect hidden-sector particles such as axions and dark photons in the ~1μeV/c^2 to ~100μeV/c^2 mass window. Our collaboration is formed from a diverse community of condensed matter physicists, quantum technologists, theorists and (astro) particle physics experimentalists. We are designing and fabricating a range of “quantum devices” and constructing a high-field, low-temperature facility at the University of Sheffield to characterise and test the devices in an axion haloscope geometry, initially using an rf cavity.

QSHS Project Launch
January 2021
Quantum Sensing for the Hidden Sector (QSHS) is a collaboration of 8 UK research institutions just approved for funding by the Science and Technology Facilities Council (STFC) under the Quantum Technologies for Fundamental Physics (QTFP) scheme announced last October. The members are The University of Sheffield (lead institution, principal investigator Prof. E Daw), University of Oxford (co-I and senior project scientist Prof. Stafford Withington) previously at University of Cambridge, Lancaster University (co-Is Prof. Yuri Pashkin, Dr. Ian Bailey, Dr. Ed Laird) The University of Liverpool (co-I Dr. Ed Hardy), The National Physical Laboratory (co-Is Dr. John Gallop, Prof. Ling Hao), University of Oxford (co-Is Dr. Peter Leek, Prof. Gianluca Gregori, Prof. John March-Russell, Prof. Subir Sarkar, Dr. Boon-Kok Tan), Royal Holloway – University of London (co-I. Prof. Phil Meeson, Prof. Stephen West). The total award was £4.7M for the QSHS group and a further £0.9M for building a test facility to search for axion.
In collaboration with ADMX, incluidng: Seattle – Chelsea Bartram, Gray Rybka, Les Rosenberg, LLNL – Gianpaolo Carosi and PNNL – Jihee Yang.
QSHS aims to solve some of the most fundamental mysteries in modern physics using new technologies being developed for the rapidly expanding field of quantum measurement science. The fundamental mysteries are the dark matter problem and the underlying structure and symmetries of quantum chromodynamics, the theory of quarks and the nuclei of atoms. The dark matter problem is the observation that galaxies and the observable Universe are heavier than their observed constituents – stars, planets, dust and gas. The extra matter making up the difference could be made up wholly or partly of ultra-light particles – the so-called hidden sector particles that have so far evaded detection. The signatures of these particles are signals so faint that the worlds most sensitive measurement devices will be developed by our team for the search. In addition, we will build a UK based experiment to conduct the search experiment itself, and to act as a faculty for further experiments. The facility will include a high field large volume magnet to induce hidden sector particles to decay into detectable electromagnetic waves and a refrigerator capable of cooling the target to around 10 millikelvin – a hundredth of a degree centigrade above the absolute zero of temperature. Detection of hidden sector particles requires very advanced low noise electronics. Devices with names like Josephson parametric amplifiers, travelling wave parametric amplifiers and Qubit arrays will be developed by our collaboration to enable the search. These devices are also critical for progress in quantum measurement and quantum computing, areas where the UK has taken a world leading position through other schemes such as the quantum hubs funded by the engineering and physical sciences research council (EPSRC). The UK researchers of QSHS will form a collaboration with the U.S. based ADMX collaboration, who operate the most sensitive detector for a particular variety of hidden sector particle, the axion. The exchange of ideas with our U.S. partners and the work we can do together will strengthen the science of both the QSHS group and their U.S. counterparts. The discovery of hidden sector particle dark matter would be a momentous event in fundamental physics. The dark matter problem is now over 50 years old, but in addition a new set of light particles would be bound to solve some of the persistent problems with the standard model of particle physics. Furthermore, hidden sector particles may play other significant roles in physics, including in early Universe cosmology and the evolution of the Universe in the moments after it came into existence. We are excited to be embarking on this journey of discovery, and we hope the British public will share in this excitement as we start this research project.
