产品概述 Product Overview

Alkali metals are widely applied in electrical doping and preparing cathode films. However, the chemical property of alkali metals is so active that it is impossible to load pure alkali metals into effusion cells without the use of the glove box or vacuum transfer box.
An alternative way is to use the Alkali Metal Dispenser (AMD), which is an efficient and safe method of depositing ultra-pure alkali metals such as Cesium, Potassium, Sodium, Rubidium, and Lithium. AMDs keep the alkali metals pure in the form of a stable salt combined with a getter material. The presence of the getter material guarantees an ultra-pure environment during the alkali metal evaporation.

Alkali Metal Evaporator is designed to be compatible with SAES AMD model X/NF/xx-/12/FT10+10 and could accept up to 3 AMDs at a time. Deposition of an individual channel or co-deposition could be chosen at the power supply. All AMDs could be easily accessed and replaced at the time of service. There are no other consumable parts on the Alkali Metal Evaporator.
