High input/output capability
Enables high input/output applications through abundant line-of-sight (LOS)
access. Up to 2 × ISO100 ports on the Secondary Insert, 2 × KF40 and 2 × KF25
on the Primary Insert.

Extensive experimental volume
Large 360 mm diameter mixing chamber plate, combined with increased
spacing to provide a large experimental volume.

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

Simple, powerful software
Maximise system value
Customisable, self-supporting Secondary Insert enhances adaptability to varied
application requirements and enables rapid exchange of full experimental set-ups.

Multi-user and multi-experiment
DC wiring, coaxial wiring, cold electronic components and samples can be fully
integrated on to multiple Secondary Inserts for easy removal, modification andexchange.

Future-proof investment
Fully cross-compatible and upgradeable Secondary Inserts can be exchanged
between current and future systems in the Proteox family.

Greater control
A patented gas gap heat switch system provides
active control of thermal conductivity between plates

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

The ProteoxTM Secondary Insert is a customisable,
self-supporting module to enable installation andexchange of full experimental set-ups.
Full experiment modularity
Moving beyond standard access ports, theSecondary Insert can accommodate fullexperimental set-ups, including DC wiring, coaxial
wiring and cold electronic components. The flexible,
modular format enhances adaptability to varied
application requirements.

Extensive wiring options
Wide selection of factory installed wiring. This has been cryogenically cycled,
factory tested and benefits from the full 3-year system warranty.

Configure for your application

Line-of-sight wiring

The Secondary Insert provides a large 117 mm ×253 mm rectangular LOS access port. This can be
configured as a single customisable plate, or with
2 × ISO100 ports and a range of standard options.

•UT34, UT47 & 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•Mount wiring and components directly onto
the Secondary Insert for unrivalled flexibility,with customisation to suit experimental set-up•

Custom configurations allow for increased
coax capacity of up to 128 UT85 lines perinsert

Signal conditioning•

Selection of attenuators for low noise quantum computing applications•Low pass filters for low electron temperature and low noise for integration,
directly onto the Secondary Insert

Integrate sample exchange
The Secondary Insert can be ordered with our patented bottom loading system
as an option. This will allow rapid sample exchange and can be coupled withmagnet integration.

Options available to enhance the utility ofyour system with customisable features for
specific application.
Magnet options
Sample pucks for rapid exchange

In-house design, manufacturing and support of both the dilution refrigerator
and the superconducting magnet provides a fully integrated system with unified
software control and data logging.

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:

Solenoid magnets•Loading a sample puck takes less than 15 minutes and the system
automatically cools back to base temperature

Range of field strengths from 1 T to 14 T•

Up to 28 RF and 96 DC connections on a single sample puck•

Ideal solution for multi-user facilities since different experiments can beprepared in multiple sample pucks•

Patented loading concept allows for safe and easy operation•

High filament count for reduced size, high sweep rate and low flux jumping•

Large bore sizes from 77 mm to 152 mm diameter across the solenoid
magnet range•

Maximum sweep rate of 2 Amp/minute•Quench protected

SampleProtect system secures against ESD
SampleProtect enables grounding or bias of samples during sample exchange
to safeguard your experiments. It provides users with an end-to-end method ofprotecting sensitive samples from accidental electrostatic discharge (ESD).
