Cryostat - Intimate Acces to the stable sample

Intimate access to the stable sample

A sample should be treated like any other optic on the table; rigidly supported and with convenient access from all sides. The cryocooler or cryostat should be a useful tool, not a hindrance that is in the way. Experimental setup and room temperature measurements in the Cryostation can be done with the sample area completely unobstructed. For lower or higher temperature work, the radiation and vacuum case can be set in place without disturbing the sample.

Cryostat - Vary temperature without sample drift

Vary temperature without sample drift

Many cryogenic systems drift hundreds of microns or even millimeters over a wide temperatures range, causing the researcher to need to re-align or re-focus optics at each new temperature set point. This is labor-intensive for the researcher and makes automation of experiments difficult or impossible. The sample mount in the Cryostation incorporates custom filament-wound materials and an engineered platform which maximizes strength and compensates for thermal contraction. This provides a rigid connection to the optics table with little or no drift with each new setpoint.

Cryostat - Vibrations are no longer a concern

Vibrations are no longer a concern

Most competitive systems sacrifice cooling power and low temperatures in order to achieve low vibrations. The Cryostation offers both low temperatures and low vibrations. Peak to peak vibrations are less than 5nm, and RMS vibrations are less than 0.25 nm. This is achieved with a patent pending design which maintains a typical base temperature of 2.8K and a typical active load cooling power of 0.1W at 4.2K with all five optical access windows in place.

Cryostat - Keep samples and optics clean

Keep samples and optics clean

Contaminates on samples and optical surfaces can degrade experiment results in a number of ways. Connect the Cryostation to clean dry nitrogen gas, and the system will automatically vent up with clean dry gas each time you warm up. This not only affects your results, but facilitates faster cooldowns too.

Cryostat - Run on low power

Run on low power

The Cryostation compressor utilizes Variable Helium Flow technology. This facilitates faster cooldowns and higher heat loads when needed, and even more importantly since the most of the time is spent at a stable temperature setpoint, the system will operate at an input power that is appropriate for the sample temperature so you are not wasting energy. The Cryostation can also run in “Standby Mode” which allows the system to stay cold while using less than 1KW of power.

Cryostat - Rock solid temperature stability

Rock solid temperature stability

Temperature drift is a problem in both liquid helium and closed-cycle systems. Using patent pending active and passive temperature stabilization, the Cryostation achieves long and short term temperature stability of less than 10mK peak to peak, even at temperatures below 4 Kelvin. The Cryostation will automatically stabilize at the temperature setpoint input by the user.

Cryostat - Powerful Electronics

Powerful electronics

A number of processes are automated by the Cryostation including vacuum pumpout, cooldown, temperature stabilization at setpoint, warmup, and purge with dry Nitrogen to keep the system surfaces, sample and optics clean. Compressor parameters are automatically optimized to minimize cooldown time, conserve power and reduce wear on the system. Diagnostics and monitoring of many system components are automatically performed, making troubleshooting a more straight-forward process for the user or a trained technician who can be networked onto the system as long as an internet connection is provided to the Cryostation.

Cryostat - Control & Automation

Control and Automation

The Cryostation is controlled with a Windows® based program running on a mini-notebook computer. Using OLE Automation, the Cryostation can be driven by another device by using LabVIEW®, for example, for total experiment automation. The Cryostation can also be monitored and controlled via any computer with internet access.

Cryostat - Electrical Access

Electrical Access

In addition to the included four thermometers and three heaters, the user is provided with 8 electrical connections into the sample area terminating with three miniature connectors. Thermal lagging locations for multiple wires are provided so that the sample stage temperature is maintained.

Cryostat - Flexibility and Modularity overhead view

Flexibility and Modularity overhead view

The Cryostation was engineered with an intentional separation of the sample environment from the cryocooler. This allows optical access from above and radially in the same system and at the same time. The flexible, modular design also allows new sample areas to be constructed and easily implemented.
