IOG 25AU

The IOG 25Au is a 25 kV high performance liquid metal ion beam system that provides a focused beam of gold ions.

Fitted with a gold-germanium liquid metal alloy ion source, a range of ions can be selected using the built-in mass filter, including Au⁺, Au⁺⁺, Au₂⁺, and Au₃⁺.

The IOG 25Au offers a wide current range with fine probe capability down to 100 nm, and can be operated in either DC or pulsed mode. It is also differentially pumped for use in a wide range of applications.
