Alkali Metals Dispensers

Alkali Metals Dispensers

Alkali Metal Dispensers (AMD) have been available from the SAES Group for over 30 years and offer an efficient and safe method of depositing ultrapure alkali metalssuch as Cesium, Potassium, Sodium, Rubidium and Lithium. AMDs keep the alkali metal pure in the form of a stable salt combine with a getter material. The presence of the getter guarantees an ultrapure environment during the alkaly evaporation.

Traditional AMD configurations in wire shape with different lengths release  few mg of alkali metal. The wire AMD are the ideal solution to manufacture photocathodes, image intensifiers and night vision tubes.

 

Highlights

  • Very pure alkali metal films
  • Controllable and reproducible alkali evaporation rate
  • No loose particles
  • Free of harmful gases during deposition of the alkali metal
  • Variety of dimensions available: wires, boats,  pills

 
Final Applications             

  • Photomultipliers
  • Night Vision Tubes
  • X-ray Image Intensifiers
  • Standard and MEMS Atomic Clocks
  • Magneto–Optical Traps
