The Proteox™ Family

Download Proteox Family Brochure
The Proteox™ dilution refrigerator enables a step change in Cryofree® system modularity - designed for enhanced adaptability, reliability and increased experimental capacity.
The compact Cryofree® ProteoxS dilution refrigerator delivers faster turnaround in a smaller size, with no compromise on performance.

ProteoxS
The largest in its class dilution refrigerator with extensive capacity for components, experimental services and sample mounting for high input/output applications.

ProteoxMX
Providing maximum qubit counts with large sample space and ample coaxial capacity for quantum computing scale-up

ProteoxLX
The world’s coldest, continuous, cryogen-free dilution refrigerator, providing ultra-low base temperature of < 5 mK and high cooling power of > 25 µW at 20 mK

Features

Future-Proof Investment
Fully cross-compatible and upgradeable Secondary Inserts can be exchanged between current (ProteoxMX or ProteoxLX) and future systems in the Proteox family.

Greater Control
Patented gas gap heat switch technology is leveraged to provide active control

Extensive Experimental Volume
Large diameter mixing chamber plate, combined with increased spacing.

Unlock New Applications
Increased capacity for components, experimental
services and sample mounting to facilitate qubit
scale-up and QIP applications.

Reliability and Convenience
New gas handling system delivers increased reliability and longer service intervals. This is combined with a new, powerful software control system.

Fast, Tuneable Cool Down
When combined with our bottom loader technology, it enables rapid cool down of sample pucks from 300 K.

High Input/Output Capability
Enables high input/output applications through abundant line-of-sight (LOS) access.

High Temperature Operation
With independent control of the experimental plate in excess of 30 K with magnet at full field and fast recovery to base temperature.

Software

  • Remote access through a web-based, platform-independent
    control software in addition to local system control
  • Automation routines for one button operation
  • Full manual control and programmable API interface for
    custom routines
  • Powerful data interrogation and visualisation package with  live plotting.
  • Step-by step wizard for guiding manual processes.

System

  • Fully redeveloped gas handling system to ensure the minimum
    number of connections and o-ring seals
  • Cross-braced stiffened frame that minimises vibration
    transmission eliminating the need for active damping
  • Modular, upgradable platform with cross-compatible  magnet systems.

Flexible Wiring

  • 24-way twisted-pair DC looms with copper, constantan or NbTi conductors
  • Flexible coaxial (S1) wiring 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.

Coaxial Wiring

  • UT34 and UT85 coax with SMA or SK connectors for 18 GHz or 40 GHz bandwidth operation
  • Range of coax conductors including stainless-steel, CuNi and NbTi
  • Heat sinking using bulkhead connectors at all experimental plates with optional 0 dB attenuators for efficient conductor thermalisation.

Attenuators

Attenuators can be selected per line and per plate; 0 dB attenuators for conductor thermalisation; 3 dB, 6 dB, 10 dB and 20 dB attenuators.

Low Pass Filters

Low-pass multi-stage filters can be mounted for use at temperatures to below 100 mK.

  • 4 cut-off frequencies available between 170 Hz and 110 kHz.
  • Gold plated copper chassis with RF gaskets to provide screening and thermal dumping for the filter PCB.

Sample pucks for rapid exchange

Our patented, market leading sample loading mechanism allows for fast and easy sample exchange, without the need to warm the
entire system to room temperature:

  • Loading a sample puck takes less than 15 minutes and the system automatically cools back to base temperature
  • Up to 28 RF and 96 DC connections on a single sample puck
  • Ideal solution for multi-user facilities since different experiments can be prepared in multiple sample pucks
  • Patented loading concept allows for safe and easy operation.

SampleProtect system secures against ESD

SampleProtect enables grounding or bias of samples during sample exchange to safeguard your experiments. It provides users with a method of protecting sensitive samples from accidental electrostatic discharge (ESD).

  • High quality, fully earthed cables for low level signals:
    Low noise
    High attenuation shielding 
  • Low cross-talk 

BNC or Twinax option.
24 connectors and 12 twisted pairs.

    Customised Magnets
    Beyond standard offering, our in-house team can design bespoke magnets to meet your experimental needs. Full FEA and electromagnet modelling capabilities ensure the integration of the magnet to the system is robust in terms of both magnet and system performance.

    Solenoid Magnets
    Range of field strengths from 1 T to 14 T.

    Vector Rotate Magnets
    Three axis vector magnets with a vertical field up to 9 T and a horizontal field up to 3 T.

    Active Field Cancellation
    Active magnetic field cancellation available for magnets up to 14 T.
