Beam flux monitor
The Beam Flux Monitor enables measurement of the beam equivalent pressure (BEP) in MBE applications.
Description
It is typically mounted on a linear shift/z-stage to allow the filament to be positioned near to the substrate and includes a protection shield when in the standby position.
Readouts and full control (device status, Z-axis shift) are provided by dedicated software application and Ion Multi Gauge Controller. Application can be integrated with Synthesium – advanced deposition software tool.
