DSM shutter assemblies can be used to rapidly change between open and closed condition, making them suitable for controlling exposure of samples to FELs and other beamlines. Each shutter is made using two opposed piezoelectric actuators with teeth that block the beam in the default condition and open to permit the beam to pass through when energized. Shutters are ultra-high vacuum compatible and options such as tungsten teeth can be incorporated. For dynamic applications, a K-type thermocouple is typically incorporated so that temperature can be monitored to prevent overheating. Please contact DSM for other options or questions.
