How to Choose a Lab Cryostat and Deal with Helium Supply Issues

Choosing the right cryostat can be a challenge, particularly when considering your long-term needs and budgetary requirements. This webinar will provide a comprehensive overview of the key factors to consider when evaluating cryostats for a research lab, including:

• Temperature stability and range, including the need for high temperature
• Types of cooling mechanisms, and their advantages and drawbacks
• Sample considerations, including the environment and vibration sensitivity
• Application and measurement requirements, such as those needed for electrical characterization, photoluminescence, or FTIR spectroscopy

We will also discuss at length initial purchase and operating costs, especially those relating to the availability of liquid helium, and whether a cryogen-free solution would better serve your needs.

By attending this webinar, you will learn:

• The types of control systems used to maintain a stable temperature in a cryostat
• The differences between sample-in-vacuum and sample-in-exchange gas cryostats
• Choices of cryostats for optical access, ultra-high vacuum environments, and magneto-transport experiments
• How to best isolate sample measurements for vibration-sensitive experiments
• Choices of optical window material for a required signal transmission range
• The pros and cons of the different types of cryogen-free cryostats
• How to simplify the integration of a cryogen-free solution into an existing application
