Cryogenic Surfaces

DynaVac has the full-house manufacturing capability to build cryogenic shrouds and panels for a multitude of sizes and configurations:

• Optically dense enclosures
• Cryogenic panels and plates
• Hardware support platens
• Contamination (scavenger) plates

We construct surfaces of aluminum and make them available with a variety of extrusions to support thermal flow requirements, making small steady-state temperature gradients achievable. Less than ± 3K is typical.

Several high emissivity coatings are available. They are selected for any specific application based on several characteristics:

• Emissivity/absorptivity values
• Temperature range
• Outgassing rate
• Ease of application and cure cycle

To assure vacuum integrity of the system, we thermally cycle panels during construction and acceptance testing and then helium leak test for further assurance.

Our final cleaning and packaging process ensures efficient, contamination-free installation.
