Slit Unit & Diagnostic Systems
Horizontal and vertical shutters, positioned inside the vacuum chamber, are translated via a single axis manipulator in order to adjust the shape of cross-sectional area of the beam. The diagnostic system includes a fully automated high precision monitor of the beam intensity and beam position, which utilises a photodiode or gold mesh. Beam profile imaging is performed by fluorescent detectors. Systems can also be equipped with temperature sensors.
Diagnostic intensity monitor allows for measurement of photoemission current and applying a polarisation voltage.
Chambers can have a granite block to reduce a vibration level.
All manipulators are motorised and software controlled.
Shutters are available with or without water cooling. Surfaces can be coated with a fluorescent material. Different material and shapes available according to requirements.
