主要特點(diǎn)：

Key Features of the Plasma Source:

Filamentless

Suitable for use with most gases including reactive gases such as oxygen， chlorine， hydrogen， nitrogen etc.

No microwave tuning

Factory set. Simply turn the plasma on and off.

User configurable

The extraction optics are designed to be quickly and easily exchanged allowing users to customise their source to suit a particular combination of sample size， working pressure and current density. Easily exchanged apertures enable beam diameter， gas load and atom flux to be optimised.

simple bakeout preparation

new bakeable ECR magnets allow simple bekeout preparation by just undoing 4 screws. The magnets do not need to be removed but are still on the air side on a closed cooling loop. Hence no sintered material is exposed vacuum.

Al2O3 plasma region

Alumina plasma cup as standard with higher yield of secondary electrons， better resistance against aggressive gases such as Oxygen and ideal plasma striking capability

compact

the air side envilope sizes are brought to a minimum of just 258mm from flange (knife edge side) to case end
