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 and signal wiring to make it suitable for many ultra-low temperature transport measurements.

Specifications

Cooling Power:  up to 12 uW at 20 mK

Solenoid magnet up to 12 T field

Easy sample access with loading taking <15 minutes

Up to 28 RF and 100 DC connections on a single sample puck

ESD protection via sample grounding or biasing before the puck docks with experimental wiring

Available with options for optical access and integrated piezo nano-positioning stages.

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
