TritonXL

We are the only company able to offer in-house design, manufacturing and support of both the dilution refrigerator and the superconducting magnet, giving you access to unique service and support capabilities of all aspects of the system.

• Solenoid magnets up to 16 T
• Two and three-axis vector magnets with a vertical field up to 8 T and a horizontal field up to 3 T
• Split-pair magnets to allow line-of sight horizontal optical access to the sample region
• Active shielding options to reduce magnetic footprint, and cancellation coils to minimise eddy current heating in swept-field experiments
• Customised magnet options for improved homogeneity, persistence stability or field resolution
• Our use of advanced superconducting wire technology guarantees the lowest possible level of flux jumping
• Magnet current leads have demountable contacts at 4 K which eliminates the need for soldering when removing the magnet
• Integrated Magnet Field Control software makes 3D field setting easy in Cartesian, cylindrical, or spherical coordinates

TritonXL has seven line-of-sight ports which allow for up to 72 semi-rigid coaxial lines to be installed, one of these ports can also be used for top-loading sample exchange. An additional seven non-line-of-sight ports are available for a variety of flexible wiring options.

Semi-rigid coaxes

• UT85 coaxes with SMA or SK connectors for 18 GHz or 40 GHz bandwidth respectively
• Standard coax materials: Stainless-steel, BeCu and NbTi
• Heat sinking using bulk-head connectors fitted at all experimental plates with optional attenuators installed at PT1, PT2 and the still
• All coax assemblies are cryogenically cycled and VNA tested in the factory

 Flexible wiring options

• 24-way twin-twisted DC looms with Constantan, Copper or NbTi conductors
• Flexible coaxial (S1) lines – for use up to 500 MHz
• Single-mode and multi-mode optical fibres
• Thermo-coaxes for effective filtering of high-frequency noise
• Low-impedance looms suitable for nano-positioning piezo devices

• A selection of cold and warm window materials with appropriate stress relief mounts to cope with thermal contraction are available, including Spectrosil B, Spectrosil WF, Sapphire, crystalline quartz, Polypropylene and Mylar
• Line-of sight vertical optical access through from the top or bottom of the cryostat
• Horizontal optical access, either line-of-sight through a split-pair magnet or via a cold mirror
• Minimal impact on base temperature: 20 mK sample temperature on bottom loading pucks demonstrated

TritonXL 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 vector 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, sample loading
• Automatic magnet de-energisation in the event of power cut, pulse tube cooler failure, or excessive heat load on second stage cooling

TritonXL 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, etc.) 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

Local technical support

• Based in the UK, USA, Germany, China, Japan, and India, We have a dedicated, qualified and experienced service team to support you with everything from installations, preventative maintenance, spares, upgrades and general queries. You also have direct access to our technical support team backed by magnet and cryogenics system engineers at our Oxford factory.
