Surface-electrode decelerator and deflector for Rydberg atoms and molecules. Schematic diagram of the surface-electrode decelerator and deflector used to manipulate beams of H₂ molecules in high Rydberg states. (i) The Rydberg state photoexcitation region is located between two parallel metal plates. (ii) The curved surface-electrode decelerator permitted controlled transport and deflection of the H₂ molecules away from their initial axis of propagation. (iii) Deflected and undeflected molecules were directly imaged on a MCP detector. From [138] with permission
