JME Portable X-Ray Betatron systems are a range of compact circular electron accelerators producing a high energy directional X-Ray beam.
JME Betatron systems are simple to operate and maintain as they contain no moving parts or cooling liquids, which aids simple maintenance, and ensuring minimal down-time.
They are capable of producing radiographs of very high contrast, sensitivity and resolution, allowing operators to meet the tightest inspection standards including ISO 17636-1, iso 17636-2. ASME and more.
JME offer 4 NDT systems within the Betatron range each with a different maximum output energy, the outputs are 2.5, 6, 7.5 and 9MeV (Mega Electron Volts).
The energy output on all systems is variable within 0.1 MeV increments enabling optimisation of contrast, image quality and safety.
Energy adjustment allows flexibility to work within image quality enhancements, safe working zones (limiting energy to reduce exclusion zones), and the ability to deploy Betatrons for a much greater range of both, less dense, and dense heavy wall objects. Allowing improved flexibility of inspection operations and services, maximising end user deployment possibilities and overall return on investment.

frequently asked questions
What is a Betatron used for?
A Betatron produces high-energy X-rays for non-destructive inspection / testing (NDT) of thick or dense materials. Typical applications include heavy-section welds, castings, valves, pressure vessels and reinforced concrete structures.
SEE INDUSTRY SECTORS >
Which JME Betatron should I choose?
JME offer Betatrons with maximum energies of 2.5, 6, 7.5 and 9 MeV. The most suitable model depends on material thickness, required image quality, exposure time and deployment conditions. Adjustable energy allows the output to be matched to the inspection, and JME can help select a suitable configuration and system type.

How much material can a JME Betatron penetrate?
Penetration depends on the model, material and inspection setup. For example, JME recommends the PXB 7.5 MeV for radiographic testing of steel welds and castings between 50–300 mm thick. Achievable results depend on geometry, detector or film selection, exposure time and the required inspection standard.
Can a Betatron be used on site?
Yes. JME Betatrons are designed for transport and assembly at inspection locations, including fabrication workshops and external sites (In-field radiography). Power and handling requirements vary by model with the 2.5/6/7.5 Mev systems being mains or battery powered. Each deployment requires suitable access and a planned radiation-controlled area. Wireless control options provide additional flexibility for remote operation.
How does a Betatron compare with Cobalt-60 radiography?
A Betatron generates X-rays electrically, providing adjustable energy without radioactive-isotope decay or periodic source replacement. For suitable applications, it can offer improved image quality and shorter exposures compared with Cobalt-60. The choice depends on material thickness, access, and inspection requirements.
