IXB-9M Betatron System

IXB-9M Radiator X-Ray Head

IXB-9M Accelerator X-Ray Head

The IXB-9M Betatron is one of a series of industrial Betatrons that produce high energy ionising radiation for industrial radiography, using N.D.T (Non-destructive testing) methods to inspect materials for defects. The IXB-9M contains few moving parts (excluding a cooling fan and a simple water re-circulation unit). There are no expensive water chilling systems or expensive vacuum devices, just a sealed glass doughnut shaped x-ray tube.

 The IXB-9M was designed for operation within a dedicated x-ray bay so careful radiation shielding design is required for operation at 9 Mev.

The IXB-9M will require a crane for manipulation due the weight of the Radiator head.

 The IXB-9M produces Radiographs of very high contrast, sensitivity and resolution.

The IXB-9M Betatron is designed for radiographic inspection of fabricated weld joints, steel and alloy castings with a material thickness in the range of 150 mm to 300 mm, concrete and other materials from 200 mm to 1200 mm. The Half Layer Value (H.L.V) for Steel is 34 mm

The x-ray film field size equals 220 mm x 220 mm @ 1 metre focal distance. In operation the IXB-9M is recommended to use 1 mm lead intensifying screens either side of the x-ray film for improved contrast.

The cost of a IXB-9M system is 50% less than other NDT accelerators such as ‘Linacs’

The weight of a IXB-9M system is about 100% less than other NDT accelerators such as ‘Linacs’

The IXB-9M replaces isotope gamma sources which will struggle to meet the same sensitivity and speed of inspection.
