Applying electron beams to 3-D objects

23.09.2016

The Fraunhofer Institute for Organic Electronics, Electron Beam and Plasma Technology FEP now has the technological means of applying electron beams very flexible to 3-D objects through use of its new electron wand of the Swiss company ebeam by COMET.

Electron beams are useful in many different applications. They reliably sterilize seed, can weld small structures precisely and reliable, and cure decorative paint. Usually this involves either planar, flexible, or slightly curved surfaces. However, applying electron beams homogeneously to 3-D objects of any size or shape has not been so simple up to now.

Scientists at Fraunhofer FEP have now elegantly combined an electron wand with a six-axis robotic manipulator in order to be able to treat substrates with complex shapes as well as spherical objects, for example.

“The electron wand remains stationary in this process”, explains Javier Portillo, a scientist at Fraunhofer FEP. “The manipulator rotates the objects within the irradiation zone in a way, that the surface will be treated homogeneously. This creates the maximum degree of freedom when applying an electron beam to a 3-D-object.”

Normally you need several electron-beam sources to treat 3-D objects. Homogeneous application does not take place reliably everywhere in this process. The process of multiaxial moving the object within the electron treatment zone can hereby generate advantages. The application of electron beams to optical components is also conceivable.

These primarily involve hydrophilic surfaces found in a wide variety of applications, such as safety glasses with antifogging coatings, diffusing screens and lenses, and anti-condensation coatings for air conditioners and sensors in medical engineering.

Scientists can apply the new technology to develop customized processes for its industrial clients that meet specific demands – including being able to treat 3-D objects with various geometries – to suit even the most diverse existing production lines.

The symbiosis of an electron beam and robotic handling can make production processes more effective and economical.

Among other places, the new technology will be presented by Javier Portillo at the 12th Ionizing Radiation and Polymeric (IRAP) symposium taking place on the Giens Peninsula in France from September 25 – 30, 2016.

Im Focus: Deep inside Galaxy M87

The nearby, giant radio galaxy M87 hosts a supermassive black hole (BH) and is well-known for its bright jet dominating the spectrum over ten orders of magnitude in frequency. Due to its proximity, jet prominence, and the large black hole mass, M87 is the best laboratory for investigating the formation, acceleration, and collimation of relativistic jets. A research team led by Silke Britzen from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has found strong indication for turbulent processes connecting the accretion disk and the jet of that galaxy providing insights into the longstanding problem of the origin of astrophysical jets.

Supermassive black holes form some of the most enigmatic phenomena in astrophysics. Their enormous energy output is supposed to be generated by the...

Im Focus: A Quantum Low Pass for Photons

Physicists in Garching observe novel quantum effect that limits the number of emitted photons.

The probability to find a certain number of photons inside a laser pulse usually corresponds to a classical distribution of independent events, the so-called...

Im Focus: Microprocessors based on a layer of just three atoms

Microprocessors based on atomically thin materials hold the promise of the evolution of traditional processors as well as new applications in the field of flexible electronics. Now, a TU Wien research team led by Thomas Müller has made a breakthrough in this field as part of an ongoing research project.

Two-dimensional materials, or 2D materials for short, are extremely versatile, although – or often more precisely because – they are made up of just one or a...

Im Focus: Glacier bacteria’s contribution to carbon cycling

Glaciers might seem rather inhospitable environments. However, they are home to a diverse and vibrant microbial community. It’s becoming increasingly clear that they play a bigger role in the carbon cycle than previously thought.

A new study, now published in the journal Nature Geoscience, shows how microbial communities in melting glaciers contribute to the Earth’s carbon cycle, a...
