PIPELINE CRAWLERS • PORTABLE X-RAY BETATRON • DIGITAL RADIOGRAPHY

The PXB2.5D portable X-Ray Betatron is designed to produce high energy ionising radiation for industrial radiographic non-destructive testing. Half Value Layer (HVL) for Steel is 20mm (0.8″)

The PXB2.5D portable X-Ray Betatron contains no moving parts (excluding cooling fan) and no circulating liquids, radiation outside the main beam is low, so safe working distances are moderate. After demarcation of dose rate boundaries, the betatron may be used at external sites or in fabrication workshops with little or no additional screening.

The PXB2.5D produces radiographs of very high contrast, sensitivity and resolution. The PXB2.5D is recommended for radiographic testing of weld joints and castings with a steel thickness of 30 to 120mm (1.2″ to 4.7″) , concrete and other materials from 100 to 300mm (3.9″ to 11.8″). The irradiation field equals 350mm x 350mm @ 1M (13.8″ x 13.8″ @ 39.4″) focal distance. In operation the PXB2.5D has no need for compensating filters that i mproves the uniformity of the radiation field. The PXB2.5D is far less costly than other NDT accelerators such as ‘Linacs’.

The PXB2.5D 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.

APPLICATIONS:

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, thick welds, composites, reinforced concrete buildings, bridges and cargo/security scanning solutions.

BETATRON/CYCLOTRON

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.

The JME PXB:2.5 Portable X-Ray Betatron is now available in a number of configurations to greatly increase its operational use. Including safe, reliable battery operation and RF wireless control.

JME’s Wireless Betatron system is compatible with the PXB:2.5 and is designed to function with both the conventional wired control panel and the innovative wireless handset. Coupled with a JME Radio Repeater the user can now operate the system from a range of up to 1,7KM. This has improved safety and allows the Betatron to be used in a greater range of inspection applications.

Our updated touchscreen Control Panel has been developed to incorporate Data Logging, Wireless Connectivity secured with 128bit encryption, a new Intuitive User Interface and optional software for data review via USB.

The Handset allows the user to wirelessly configure the system prior to operation. Providing real time feedback on the status/operation of the system whilst in use. The operator can review and adjust parameters which are key to operation, including the output of the system, exposure time, and both real time and accumulated dose rates. With Safety at the Forefront of Design, the user has continuous access to an emergency stop feature, and in the unlikely event communication is lost, the system will stop any exposure being carried out.

Utilizing the power of the JME:PBU, Portable Battery Unit, it is now possible to power the system in locations where mains power isn’t available or unreliable. With no reduction in PXB:2.5 specification or functionality, the JME:PBU will give the system 90 minutes of X-Ray on time with only a 2.5 hour charge (per PBU). The JME:PBU removes the need for flammable liquids on site for use with generators, reduces overall deployment weight, improves access to hard to reach and hazardous locations, while removing the need for maintenance and risk of unplanned break downs.

The JME:PBU replaces a standard 230V wall socket and has a rated power output of 3600W, 16A, powering your most demanding equipment. It has a robust and weather-proof IP54+ rating so can work in the most demanding of environments, unaffected by dust or water. The unit can be transported safely simply by enabling Transport Mode, this allows the unit to be shipped in accordance with SP188.
