Wiring and Signal Conditioning
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 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 Loader
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
Magnets
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
