Io is a compact, Cryofree® and low vibration continuous cooling solution offering device and sample temperatures down to 50 milliKelvin (mK). Io comes in application-friendly configuration packs for:
low temperature detectors
Io is ideal for sub-100 mK research and detector applications, offering continuous running together with lower device and lower sample temperatures compared to ADR and 3He refrigerators. It enables easy integration of a wide range of optical accessories such as windows, optical fibres, piezo-electric manipulators and neutron scattering tails, which together with a powerful 1 K circuit makes this system the perfect choice for quantum photonic measurements, detector development and beam-line applications.
Io builds on Oxford Instruments’ leading expertise in Cryofree technology, brought into a new, compact footprint for specific applications. Because it is built on dilution refrigerator technology, it not only offers the continuous cooling associated with dilution refrigerators but also the space and integration benefits that other techniques cannot offer.
Compact, lightweight and mobile
Easy to install and operate where space comes at a premium or when the system needs to be to be frequently moved from one place to another. Re-commissioning this system does not require factory expertise - it is designed so that inexperienced users can do this work with minimum effort.
Excellent temperature control
The sample plate can be controlled between 50 mK and 10 K, while maintaining the magnet at full field. The temperature stability is: ± 1 mK below 100 mK, ± 1% above 100 mK. There are no unstable temperatures regions, the sample plate can be controlled accurately at any intermediate temperatures. An example of a temperature controlled sweep in steps of 100 mK is shown below.
Dedicated 1 K stage
This powerful intermediate stage is ideal for anchoring wires and other experimental services.
Fast cool-down time
The system cools from room temperature to base (<50 mK) in <24 hours.
1W pulse-tube cooler decoupled with flexible copper braids.
The mixing chamber plate is 150 mm diameter.
One 50 mm line-of sight port for up to eight semi-rigid coaxes and three more ports for flexible wiring.
Ease of assembly
The vacuum cans and radiation shield flanges have key-way holes, which makes the cryostat easier to assemble by a single person.
Ease to use
Bolted magnet current leads (no soldering required).
Io strikes the perfectly balance between performance and affordability for many applications. With a 50 mK base temperature, 30 µW of cooling power at 100 mK and continuous operation over a wide temperature range.
