The JME Portable Betatron is a compact circular electron accelerator producing a high energy directional X-Ray beam. Containing no moving parts except small airflow fans, and no circulating liquids, the Betatron is easy to assemble, operate and maintain.
Interlock able to safety systems or supplied with a stand alone audio visual warning system. The Betatron produces radiographs of very high contrast, sensitivity and resolution, meeting the tightest inspection standards.
It can replace cobalt isotope gamma sources, which may not give acceptable quality and require costly periodic replenishment.
Compared to cobalt, the Betatron's shot time is drastically reduced and the extremely small focal spot size provides a sharper, higher quality radiograph, thus increasing production rate and profit.
JME’s range of Betatron systems have been supplied for a wide variety of applications within many sectors of the NDT industry. Examples of the work we have previously supplied systems for include but are not limited to the inspection of Large forgings, castings, valves, beams, ships hulls, pressure vessels, engine blocks, billets, thick welds, munitions, composites, propellants, reinforced concrete buildings, bridges and cargo/security scanning solutions.

A Betatron Portable X-Ray System is a type of Cyclic Particle Accelerator, in some areas of the world, these systems are also referred to as a Cyclotron X-Ray System. Betatron systems include a Torus-shaped vacuum tube which house electrons as they are accelerated around a circular path using alternating current, and then ejected at a specific target once they have achieved the required velocity.
The main difference between the Betatron and Cyclotron systems is that the Cyclotron uses magnetic fields to bend the particles into a circular path and a pulsing electromagnetic field to increase the speed of the particles. The Betatron systems only use magnetic fields to increase the speed of particles.
