XRS1-800/1600 Fast Piezo Shutters Description The XRS1-800 and XRS1-1600 are two versions of a shutter assembly that 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. • Flexure-guided for smooth, parallel motion • UHV Compatible Specifications • High natural frequencies and rapid response • Customizable and scalable for new applications XRS1-800 Typical Operating Voltage (V): First Translational Natural Frequency (Hz) : Minimum Recommended Rise/Fall Time (ms) : Stainless steel Stainless steel Nominal Open-loop Travel per Actuator (µm) * Shutter Opening specifications includes a 75µm overlap at zero volts.
