Linear Accelerator Testing (LINAC)
Accelerate inspections without compromising on quality or support. Our Linear Accelerator Testing (LINAC) delivers end-to-end convenience, speedy radiographic results, and hands-on technical guidance for thick steel castings and smaller components. Partner with Element to ensure you meet demanding schedules, strengthen compliance, and maintain complete confidence in every result.

What is Linear Accelerator Testing (LINAC) at Element?
Linear Accelerator Testing is a non-destructive testing method that uses high-energy radiation to detect defects in materials. At Element, our 6MeV Linear Accelerator emits powerful X-rays to efficiently inspect thick steel components, revealing flaws such as porosity, inclusions, and cracks that might otherwise remain hidden. Based at the Sheffield Forgemasters site, Element is one of the few companies in the UK to offer this service. While ideally suited to large steel sections, our LINAC also speeds up inspection on smaller, more complex pieces.

What Can Element Offer You For Linear Accelerator Testing ?
Materials We Test
