ProteoxS

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.

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

Solenoid Magnets

12 T solenoid magnet with 57 mm bore
High filament count for reduced size, high sweep rate and low flux jumping
All magnets ramp to full field in 1 hour or less
Persistence mode switch

Vector Rotate Magnets

6,1,1 T 3 axis vector rotate magnet with a 77 mm bore
Maximum field for 360° vector rotation: 1 T vector magnitude in sphere
Vector tilting angle 2.5° from vertical axis with a vector magnitude of 6 T

The compact Cryofree® ProteoxS dilution refrigerator delivers faster turnaround in a smaller size, with no compromise on performance.
