Platform Solutions

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

System

Reduced ceiling height requirement to suit common research laboratories
Cross-braced stiffened frame that minimizes vibration transmission eliminating the need for active damping
Lighter vacuum cans and shields removes the need for lifting equipment

Options / Accessories

Flexible Wiring

24-way twisted-pair DC looms with copper, constantan or NbTi conductors
Flexible coaxial (S1) wiring for DC or low frequency
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 connectors for 18 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.

Our patented bottom loader and active gas gap heat switch technology enable fast sample turnaround times with sample puck cooldown times in less than 8 hours, particularly suited to magnet systems and for qubit screening.

Easy sample exchange without the need to warm the entire system to room temperature
Loading a sample puck takes < 15 minutes and the system automatically cools back to base temperature
Up to 22 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
ESD protection (make-before-break) via sample grounding or biasing before the puck docks with the system.
Cooling power up to 150 μW at 100 mK
Base temperature < 12 mK
