Linear electron accelerators with energies from 3 to 7 MeV
Linac oration pmb inspection non destructive testing beam line

PMB has developed a range of S-band electron linear accelerators (LINAC) called NDT ORIATRON with energies varying from 3 to 7 MeV to generate an X-ray beam, which can penetrate steel thicknesses up to 310 mm for the analysis of possible defects.

Their maintenance is performed by our technical teams, who keep spare parts in stock, guaranteeing fast turnaround and minimum machine downtime.

Our system has a unique advantage : its reduced focal spot allows to get sharper images. Combined with a 2D and 3D imaging system, it is particularly suitable for non-destructive testing.

The NDT ORIATRON can be placed on an elevating table in order to have vertical movement or it can be attached on a manipulator to ensure its movements in 3 directions.

Several options are available, which allows our LINAC to better meet the specific requirements of each project.

PMB provides linacs with the following nominal energies: 3 MeV, 4 MeV, 6 MeV and 7 MeV. These standard ranges have several options catering for the specific requirements of each project. By means of simulations, calculations and study, PMB develops specific machines for particular applications. These cases have required the development of specific secondary collimators, beam flatteners and operation in the green zone (self-shielded machines).

PMB uses 3D HFSS electromagnetic simulation software for the design and sizing of RF components. Egun code is used to simulate the movement of charged particles and is used for the sizing of electron guns.

The complete architecture is validated by simulation in beam dynamics. The machine high-voltage circuits are simulated using SPICE software. All PMB accelerators are fully tested at PMB before being installed at customer sites, demonstrating full compliance with specifications.

Focal Spot

The downsized focal spot size (0.6 mm to 0.7 mm, depending on the measurement method) allows the imaging system to produce greater image resolution, making it easier for the operator to detect even the smallest defects, voids, inclusions, etc. Moreover, this feature allows the object to be closer to the source, resulting in a higher dose rate.

The electron gun generates a beam, which is accelerated to the required energy through a section then converted into bremsstrahlung X-rays, using a tungsten conversion target.

The LINAC’s core, the beamline, is composed of these essential elements, which are entirely designed and manufactured by PMB.
