Introducing a new generation 2016 Triton fridge for high power and enhanced sensitivity in quantum technologies and ultra low temperature physics
08 March 2016

Oxford Instruments is unveiling its 2016 new generation Triton Cryofree® dilution refrigerator at a series of high-profile physics conferences this month. With over 220 systems installed worldwide, Triton is used in world-leading research across condensed matter physics, with a particular focus on advanced computing, quantum technologies, spintronics and optics. The new generation Triton system continues to provide market leading performance and reliability, with enhanced cooling power, ease of use, user access and experimental space.

Dilution refrigerators are used by physicists to achieve ultra low temperatures below 10 milliKelvin – that is, within 0.01 °C of absolute zero – to observe, understand and control materials and devices at their fundamental limits in order to develop techniques and technologies of the future.

Such ultra low temperature experiments now frequently extend well beyond the sample or device itself, to incorporate signal conditioning such as high frequency qubit read-write control lines, low radiation environments for quantum sensor detection, and ultra low vibration systems for pump-probe experiments. These all create growing demands for space, cooling power and performance, which the new generation Triton has been designed to answer.

The new generation Triton system design gives far-reaching benefits. Latest 7th series high cooling power DU7 dilution units give enhanced sample cooling powers of 500 µW at 100 mK and 15 µW at 20 mK as standard, without increased volumes of costly 3He. Larger diameter plates at intermediate temperatures and the mixing chamber give greater capacity for wiring, filtering, signal attenuation and other RF signal chain components to be easily accommodated, while a range of larger, heavier and more complex integrated superconducting magnets are also made possible. The new high-rigidity support structure reduces low frequency modes and harmonics within the cryostat to provide ultra low vibration characteristics for sensitive measurement needs. Simplified single-user system assembly and a new system control rack are among the new ergonomic features.

Oxford Instruments’ unique offering of both top- and bottom-loading mechanisms for rapid, protected sample exchange while preserving base temperature performance remains a key feature.

“We are excited to bring the new generation Triton to experimentalists in quantum computing, quantum technologies, and condensed matter physics,” comments Dr John Burgoyne, Marketing Director at Oxford Instruments NanoScience. “Together with our recent announcement on the Nanonis Tramea quantum transport measurement system, we are continuing our focused commitment to bring the highest possible experimental capabilities to our customers. Our technology team have done a fantastic job in pre-empting and incorporating our customers’ needs as well as innovative low temperature engineering into this new generation product.”

Oxford Instruments will be present to discuss the new 2016 Triton dilution refrigerator at a number of key physics conferences in March, including the DPG (Regensburg, Germany, 6-11 March), APS (Baltimore, MD, USA, 14-18 March), JPS (Tohoku Gakuin University, Japan, 19-22 March) and JSAP (Tokyo Institute of Technology, Japan, 19-22 March) Spring Meetings.
