Overview
General Description
Triton™ dilution refrigerator is a versatile Cryofree® research tool for applications in quantum technology and condensed matter physics at temperatures < 10 mK. It is equipped with a superconducting 12 Tesla magnet, bottom sample-loading mechanism, signal wiring and optical windows to make it suitable for any ultra-low temperature measurement.

Technology Overview
Triton cryogen free dilution refrigerators are software controlled via a high quality PC running Windows 10, providing system automation of refrigerator routines and programmable temperature/field sequences.
System automation
- Fully automatic cool-down/warm-up routines
- Fully automatic pre-cooling/mixture collection
- Sample change wizard for systems with bottom- or top-loading sample exchange load-locks
- Fully integrated magnet control via our magnet field control software, making field setting easy, even with vetor magnets in two or three dimensions
Experimental control
- Programmable temperature and field sequences
- Programming library supplied with example LabVIEW VIs
- Integration of dilution refrigerator / magnet control and experimental data acquisition
In-built safety features
- Continuous monitoring of all pressure gauges
- System automatically enters 'safe state', if necessary
- Automatic software intervention in case of over pressure with fail-safe in-line pressure relief valves, protecting the mixture and dilution refrigerator in the event of extended power failures
- UPS option – automatic alert emails can be sent to user in the event of a power failure
- Monitoring of magnet temperature during field sweep, high temperature control and sample loading
- Automatic magnet de-energisation in the event of power cut, pulse tube cooler failure, or excessive heat load on second stage cooling
Triton command interfaces
- Platform independent remote scripting interface
- Standard internet (TCP/IP) protocol
- Compatible with any programming language that can access the TCP port e.g. LabVIEW / Matlab / Python / C / C++ / C# / Visual Basic / HP VEE, etc.
- Monitoring and control of automatic software routines and system parameters
- Definable access levels (read only/read-write) with security
User support
- Remote system access by Oxford Instruments support staff can be enabled to aid system diagnostics
- All system settings are backed up prior to shipping from the factory
