Oxford Instruments’ Triton Cryofree dilution refrigerator

Oxford Instruments is pleased to announce that its TritonTM Cryofree® dilution refrigerator has been chosen to support the development of quantum electronic technologies at the University of Oxford. The Triton dilution refrigerator enables scientists to cool samples and devices to a base temperature of less than 10 mK, and there are over 250 systems installed worldwide in leading Universities and research institutes. This is this third Triton system to be installed at the Materials Department in Oxford University, and like the previous systems it is equipped with a 6/1/1 Tesla vector rotation magnet and Oxford Instruments’ market leading bottom-loading sample exchange mechanism. The sample loading functionality substantially reduces the sample turnaround time of the system, from around two days to less than 8 hours without compromising the achievable temperature.

“We are happy to use Oxford Instruments’ considerable experience in application areas related to quantum technology. The Triton system is a quantum-ready cryogenic platform that allows us in our project to develop advanced quantum nanodevices using this technology. We are particularly keen on the inter-changeability of Oxford Instruments’ sample pucks between our various refrigerators”, says Professor Andrew Briggs.

Quantum science and technology provides new techniques for sensing, measurement, information processing, data transmission and storage. Oxford University researchers are aiming to set new standards for research and training, ranging from fundamental quantum physics to scalable quantum computers that will work with qubits (quantum bits) in place of classical bits of information. The core thrust of the research in Professor Briggs’ laboratory is to harness quantum effects in working devices, for practical quantum technologies. Some of the devices consist of a single carbon nanotube with contacts and gates, others consist of a gap only a couple of nanometres wide in a graphene ribbon with a single molecule inserted as the active element.

Oxford Instruments is proud to be a leading UK company providing state of the art research tools for the development of quantum technology applications, having extensive relationships with both the worldwide research community, and companies bringing new commercial applications to market.

Dr Gustav Teleberg, ULT & QIP Product Lifecycle Manager of Oxford Instruments NanoScience commented, “The Cryofree Triton dilution refrigerators are setting new records in enabling innovations and discoveries in quantum technology areas. We are delighted to be able to supply yet another Triton dilution refrigerator to Dr Briggs’ laboratory.”
