Triton High power and enhanced sensitivity in Quantum Technologies and ultra low temperature physics

Our new generation Triton Cryofree® dilution refrigerator – high power and enhanced sensitivity in quantum technologies and ultra low temperature physics. With over 260 systems installed worldwide, TritonTM 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.

NEW cooling power – 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
NEW large experimental space – a new, larger 290 mm mixing chamber plate gives Ø290 x 240 mm sample space below it. More space on all the experimental stages means 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
NEW design features for easiest operation and highest reliability 
Low vibration for the most sensitive experiments
Complete magnet integration – only Oxford Instruments is able to offer in-house design, manufacturing and support of both the dilution refrigerator and the superconducting magnet
Fast sample change and maximum sample size – unique top- and bottom-loading sample puck mechanisms for rapid, protected sample exchange while preserving base temperature performance
The Triton guarantee: 3 years comprehensive warranty including all supplied third party components, such as the pulse-tube cooler, pumps and electronics – all backed by our expert regional service teams, for complete peace of mind

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.
