X-ray Analyzers

Beam stopper:

▪ Used to catch the primary X-ray beam if the material to be analysed is not available when the device is
ON.

▪ Should be fixed to the X-ray unit.

▪ Should be placed close to the aperture of the tube housing to attenuate the dose to below the limit

specified.

▪ Should be interlocked with the X-ray tube so that removal of the unit immediately de-energises the X-

ray tube or closes the shutter.
