An integral shutter that is for use in several beamline applications. The shutter combines the features and properties of a pink beam photon shutter, a pink beam safety shutter, a pink beam fixed mask and a pink beam collimator. The device is important for synchrotron radiation facility personal safety. These assemblies are needed to guard against accidental positron beam loss during both injection and normal operation. Positron beam loss can result in high-energy radiation being directed into an experimental station.
