Announcing the launch of Io – the most compact and easy to use Cryofree continuous cooling solution for milliKelvin devices  
31 October 2016

Oxford Instruments is pleased to announce its latest new product within the Cryofree® cooling systems family – the Io. As part of the company’s ongoing innovation strategy, the launch of Io will further expand the scope of scientific applications to be performed by the research community.

Io is pre-configured to suit a range of different measurements, with packages of experimental services which include optical windows, magnetic shielding, optimised signal wiring and integrated superconducting magnets. The low temperature detector applications include transition edge sensors (TES), kinetic inductance detectors (KID) and single photon detectors (SPD); a specific package offers qubit and quantum device characterisation, while a final pack targets neutron scattering applications.

Io provides detector, quantum device and beam-line scientists with a more compact and convenient milliKelvin solution than conventional refrigerators. Up until today, adiabatic demagnetisation refrigerators (ADRs) have been the mainstay cooling technology on offer, but these systems suffer from a number of operational disadvantages. ADRs  provide very limited cooling power which makes integration of experimental services more difficult, and their single-shot operation interrupts the measurements typically once every 24 hours. Because Io is built on dilution refrigeration it offers fully continuous operation and far higher cooling power but crucially, it does so without the added bulk and complexity usually associated with this technology. Cooling stages at 4 K and 1 K, offer intermediate experimental stages for signal conditioning elements. Io has been streamlined to meet the requirements for cooling quantum sensors, cryogenic detectors and neutron scattering samples. Its compact form factor also makes it easier to install where space is limited and to move the system from one location to another.

“Quantum sensors and cryogenic detectors will play an important role in physical sciences, quantum communication, medical and security screening. We are delighted to bring this new product to the market to help developing future quantum technologies for these very exciting applications”, said Dr Gustav Teleberg, Product Lifecycle Manager at Oxford Instruments NanoScience. “Our recently launched new generation Triton will continue to satisfy the majority of milliKelvin applications due to its versatile design and powerful performance. TritonXL is being widely used for quantum computing and with the introduction of Io, we open up a wide range of applications for the detector market”, added Teleberg.

Oxford Instruments has started taking orders for Io systems; the product will be further showcased at the upcoming conferences across the globe.
