Ionic Current Measurement
The Faraday FCB cup, connected to a source meter (Source Meter), is used to collect and measure currents of charged particles, such as those emitted by a source of ions.
The FCB is mounted on a standardized vacuum flange, allowing for easy installation in the vacuum system. The Faraday cup is UHV compatible (ultra high vacuum) and consists of a hollow stainless steel cylinder, closed at the base and with an aperture sized properly for the collection of electrons or ions.
The FCB has a standard opening diameter of 2.0 mm. However, custom opening sizes are also available. The Faraday cup is electrically connected directly to two BNC connectors, which can then be connected to a source meter.
Beam current diagnosis for ion and electron sources
High resolution measurement of charged particles in the power range of up to 1500 EV, suitable for UHV applications.
Design compatible with UHV and thermally stable
Fully heated stainless steel body with PTFE insulation, safe for continuous operation in processes up to 180 °C.
System compatibility and EMC optimized signal routing
DN 40 ISO-KF flange, HV-BNC connector up to 5 kV and grounded opening to minimize noise components.
