Linear Accelerator 

LINACLinear Accelerator for generating high-energy X-rays. These are used for medical purposes as well as for NDT. Generally, the LINAC is used in a fixed radiography facility for the inspection of thick section materials. Recent developments in portable LINAC systems offer the potential for further NDT applications.

The LINAC used for NDT comprises a high-voltage supply, a pulse modulator, a microwave generator, an electron source, an accelerator and a target. The basic principle of operation is the use of microwave energy to create electric fields. The electric fields are then used to accelerate electrons into a metal target to produce the X-rays.
