New Portable X-Ray Tube from GE Inspection Technologies


For efficient radiography with high geometric magnification and reduced exposure times

  • Increased X-ray inspection productivity by 3-5 times reduced exposure times
  • Small focal spot for radioscopic film inspection and Computed Radiography (CR) where geometric enlargement is required

The new portable ERESCO 300 MF4-R X-ray tube brings inspection time reduction and geometric magnification to film based and digital radiography.

It completes the already successful range of field-proven industrial high power X-ray tubes from GE Inspection Technologies. The ERESCO MF4 series finds application throughout the industrial spectrum in the inspection of welds and in the examination for structural integrity offering a comprehensive solution to meet all customer needs in portable X-ray.

The heart of the innovation is a completely new design of the X-ray tube, yielding an enormeous advantage of versatility and performance. As Juan Mario Gomez, General Manager Radiography at GE Inspection Technologies, comments:

“When engineering the new tube, we have listened to our customers demanding improvements for standard film als well as for the increasing application field of portable radiography in fields such as oil and gas industry, aerospace, aircraft or power plant inspection. The resulting tube combines the advantage of the 300 kV high voltage range with a by a factor 3 smaller focal spot compared to GEs present ERESCO 64 MF4 tube. This offers excellent penetration, sharper results and shorter exposures as well as geometric magnification inspection to facilitate higher productivity and quality in day-to-day inspection routines.”

Moreover, the by the smaller focal spot reduced unsharpness enables a further step towards field inspection in combination with GE’s CR technology or portable digital detectors.

Designed for reliability in some of the world’s toughest inspection conditions, the new ERESCO model as part of the well-known ERESCO MF4 familiy consists of a sturdy metal-ceramic X-ray tube and high voltage generator integrated in a robust rugged housing including a protection cover and carrying grip. The 300 kV / 900 W end-grounded X-ray tube is thermally protected for extended life.

The insulation is by gas rather than oil to reduce the overall tube weight and ensures ease of field inspection. The control module offers intuitive operation and highly visible, full graphic, trans-reflective display, with on-board exposure calculator and menu-driven setup and operation.

It can be conveniently operated in a number of user-selected positions. There is constant monitoring and display of temperature, pressure and mains voltage. Event logging and interpretation is shown on the graphical user interface, which also guides users through selected setup or inspection procedures, as well as through fault correction processes.

Robust design and IP 65 certification fit all ERESCO units for operation in wet conditions and ensure highest duty cycle operation under ambient temperatures at 30°C and above.

Im Focus: Etching Microstructures with Lasers

Ultrafast lasers have introduced new possibilities in engraving ultrafine structures, and scientists are now also investigating how to use them to etch microstructures into thin glass. There are possible applications in analytics (lab on a chip) and especially in electronics and the consumer sector, where great interest has been shown.

This new method was born of a surprising phenomenon: irradiating glass in a particular way with an ultrafast laser has the effect of making the glass up to a...

Terahertz excitation of selected crystal vibrations leads to an effective magnetic field that drives coherent spin motion

Controlling functional properties by light is one of the grand goals in modern condensed matter physics and materials science. A new study now demonstrates how...

Im Focus: New 3-D wiring technique brings scalable quantum computers closer to reality

Researchers from the Institute for Quantum Computing (IQC) at the University of Waterloo led the development of a new extensible wiring technique capable of controlling superconducting quantum bits, representing a significant step towards to the realization of a scalable quantum computer.

"The quantum socket is a wiring method that uses three-dimensional wires based on spring-loaded pins to address individual qubits," said Jeremy Béjanin, a PhD...

Im Focus: Scientists develop a semiconductor nanocomposite material that moves in response to light

In a paper in Scientific Reports, a research team at Worcester Polytechnic Institute describes a novel light-activated phenomenon that could become the basis for applications as diverse as microscopic robotic grippers and more efficient solar cells.

A research team at Worcester Polytechnic Institute (WPI) has developed a revolutionary, light-activated semiconductor nanocomposite material that can be used...

Im Focus: Diamonds aren't forever: Sandia, Harvard team create first quantum computer bridge

By forcefully embedding two silicon atoms in a diamond matrix, Sandia researchers have demonstrated for the first time on a single chip all the components needed to create a quantum bridge to link quantum computers together.

"People have already built small quantum computers," says Sandia researcher Ryan Camacho. "Maybe the first useful one won't be a single giant quantum computer...
