IXB-2.5M Betatron System

The IXB-2.5M Betatron is one of a series of industrial Betatrons that produce high energy ionising radiation for industrial radiography.  It uses N.D.T (Non-destructive testing) methods to inspect materials for defects.  The IXB-2.5M has no moving parts other than cooling fans. There are no expensive water chilling systems or expensive vacuum devices, just a sealed glass doughnut shaped x-ray tube. Radiation outside the main beam is manageable, so safe working distances are moderate with conventional shielding methods. The IXB-2.5M was designed for operation within a dedicated x-ray bay, but as the system is easily portable with careful calculation of controlled area boundaries, the Betatron may be used for field based inspections or within manufacturing workshops.  (Subject to local Radiation approval).

The IXB-2.5M produces Radiographs’ of very high contrast, sensitivity and resolution that will be hard to match.

The IXB-2.5M Betatron is designed for radiographic inspection of fabricated weld joints, steel and alloy castings with a material thickness in the range of 30 mm to 120 mm, concrete and other materials from 100 mm to 300 mm. The Half Layer Value (H.L.V) for Steel is 20 mm

The x-ray film field size equals 350 mm x 350 mm @ 1 metre focal distance. In operation the IXB-2.5M is recommended to use 1 mm lead intensifying screens either side of the x-ray film for improved contrast.

The cost of an IXB-2.5M system is 50% less than other NDT accelerators such as ‘Linacs’

The weight of an IXB-2.5M system is about 300% less than other NDT accelerators such as ‘Linacs’

The IXB-2.5M replaces cobalt isotope gamma sources which will struggle to meet the same sensitivity and speed of inspection.


Castings, steel beams, valves, nuclear pressure vessels, cooling pipes, oil pipes, engine castings, railway composites, flexible flow lines, munitions, solid propellants, Concrete structures, bridge tension cables, and many more examples yet to be inspected.
