AERI BB Top Level Design Choices
Cavity Approach
- Provides high emissivity
- Emissivity enhancement due to cavity is well characterized
- Cavity walls provide good conduction (low gradients
- Easy manufacture
-
Chemglaze Z306 Paint
- Provides high emissivity that is well characterized and stable
- Provides a hardy surface
Thermistor Temperature Sensors
- Very Stable (0.01 K drift after 100 months at 70 K)
- Easy to couple thermally to blackbody cavity
- Reasonably rugged
