Photon shutters and stoppers are the safety-critical gatekeepers of every synchrotron beamline. JJ X-Ray designs and manufactures UHV-compatible shutter and stopper systems for reliable, fail-safe beam interception — from fast white-beam shutters with milliseconds crossing times to tungsten photon stoppers engineered for worst-case, full-power scenarios. Water-cooled absorbers, fail-safe pneumatic actuation, double position feedback, and anti-fall safety features come standard, and every system is tailored to your beamline’s heat load, vacuum, and safety requirements.
