The ARS range of Closed Cycle Cryogenic Probe Stations provides a cryogen free, high vacuum platform for electrical, RF and optical characterisation of devices across an exceptionally wide temperature range.
Designed for research and production environments, these systems enable repeatable low temperature measurements without the cost, complexity or downtime associated with liquid cryogens.
Closed cycle operation allows users to perform consecutive device measurements without breaking vacuum or rewarming the system, significantly improving throughput and measurement consistency. The modular design of the ARS probe station platform supports a wide range of probe, wiring and optical configurations, allowing systems to be tailored to specific experimental requirements.
Closed Cycle Cryogenic Measurement Capability
ARS closed cycle probe stations operate from below 4 K up to 800 K when equipped with the high temperature interface. This wide operating range supports characterisation of semiconductor, photonic and quantum devices under realistic thermal conditions using a single platform.
High vacuum operation ensures thermal stability and low contamination, while closed cycle cooling eliminates the need for liquid helium or nitrogen. This makes the system well suited to long duration testing and unattended operation.
Probe and Measurement Flexibility
The ARS closed cycle platform supports up to eight independent probe arms with positioning sensitivity down to 5 μm. A 2 inch, 50.8 mm diameter measurement area accommodates a wide range of sample sizes and device layouts.
Low vibration performance of less than 1 μm enables stable probing at cryogenic temperatures, supporting sensitive electrical and RF measurements. Rapid sample cooldown further enhances efficiency in high throughput research and test workflows.
Electrical, RF and Optical Integration
Custom wiring configurations are available to support DC and microwave measurements up to 67 GHz. This enables characterisation of high speed and RF devices without compromising thermal or mechanical performance.
Large optical access ports allow straightforward integration of optical instruments such as lasers, spectrometers and detectors. For precision sample alignment and inspection, an optional 7:1 zoom microscope with integrated ring light is available.
Typical Applications
ARS closed cycle cryogenic probe stations are widely used for:
- Semiconductor device characterisation
- RF and microwave testing at cryogenic temperatures
- Quantum and superconducting device research
- Photonic and optoelectronic measurements
- Material and reliability studies across wide temperature ranges

What is a Closed Cycle Cryogenic Probe Station?
A closed cycle cryogenic probe station is a measurement platform used to electrically, RF and optically characterise devices at cryogenic and elevated temperatures without the use of liquid cryogens. Cooling is provided by a closed cycle refrigerator, allowing stable, repeatable temperature control under high vacuum conditions while enabling consecutive measurements without breaking vacuum or warming the system.
Key characteristics of closed cycle cryogenic probe stations:
- Closed cycle cooling eliminates the need for liquid helium or nitrogen, reducing operating costs and simplifying laboratory operation.
- Supports device testing from cryogenic temperatures up to elevated ranges using a single, configurable platform.
- Maintains a clean, stable vacuum to ensure thermal stability and repeatable electrical performance.
- Designed for accurate probe placement and stable measurements, even at very low temperatures.
