Plasma Sheath Dynamics

Boundary layer between plasma and surfaces

Full Analysis

Intel Stream Decrypted

The Plasma Sheath is a boundary layer that forms between bulk plasma and any surface. Due to electron mobility, surfaces acquire negative charge, creating an electron-depleted region (sheath) with strong electric fields. Sheath thickness is typically several Debye lengths. Understanding sheath dynamics is crucial for interpreting sensor readings near any physical boundary.

Strategic_Takeaway

"Plasma sheaths create strong fields near surfaces—account for sensor placement."
