What is 3D-MID? Molded parts with integrated electronics from HARTING

3D-MID (three-dimensional mechatronic integrated devices) tech combines electronic and mechanical functionalities into a single, 3D component. It replaces the traditional printed circuit board and opens up many new opportunities. It takes injection-molded parts and uses laser-direct structuring to etch areas of conductor structures, which are filled with a copper plating process to create very precise electronic circuits. HARTING, the technology's developer, says it's "Like a PCB, but 3D." Tons of possibilities.

Researchers create miniature particle accelerator the size of a computer chip

Particle accelerators are crucial tools in a wide variety of areas in industry, research, and the medical sector. The space these machines require ranges from a few square meters to large research centers. Using lasers to accelerate electrons within a photonic nanostructure constitutes a microscopic alternative with the potential of generating significantly lower costs and making devices considerably less bulky.

A team of laser physicists at the Friedrich-Alexander-Universitat Erlangen-Nurnberg (FAU) in Germany has now succeeded in demonstrating the first nanophotonic electron accelerator -- at the same time as colleagues from Stanford University. The researchers from FAU have published their findings in the journal Nature.

When people hear "particle accelerator," most will probably think of the Large Hadron Collider in Geneva, Switzerland, the approximately 27-km-long, ring-shaped tunnel that researchers from around the globe use to conduct research into unknown elementary particles. Such huge particle accelerators are the exception, however. We are more likely to encounter the devices in other places in our day-to-day lives, for example in medical imaging procedures or during radiation to treat tumors. Even then, however, the devices are several meters in size and are still rather bulky, with room for improvement in terms of performance.

In a bid to improve and decrease the size of existing devices, physicists around the world are working on dielectric laser acceleration, also known as nanophotonic accelerators. The structures they use are only 0.5 mm in length, and the channel the electrons are accelerated through is only about 225 nanometers (nm) in width, making these accelerators as small as a computer chip.

Particles are accelerated by ultrashort laser pulses illuminating the nano-structures. "The dream application would be to place a particle accelerator on an endoscope in order to be able to administer radiotherapy directly at the affected area within the body," explains Dr. Tomas Chlouba, one of the four lead authors of the recently published paper. This dream may still be far beyond the grasp of the FAU team, but they have succeeded in taking a decisive step in the right direction by demonstrating the nanophotonic electron accelerator device.

"For the first time, we really can speak about a particle accelerator on a chip," says Dr. Roy Shiloh, one of the paper's authors.

Guiding electrons + acceleration = particle accelerator
Just over two years ago, the team made their first major breakthrough: They succeeded in using the alternating phase focusing (APF) method from the early days of acceleration theory to control the flow of electrons in a vacuum channel over long distances. This was the first major step on the way toward building a tiny particle accelerator. Then, all that was needed to gain major amounts of energy was acceleration.

"Using this technique, we have now succeeded not only in guiding electrons but also in accelerating them in these nano-fabricated structures over a length of half a millimeter," explains Stefanie Kraus, also one of the paper's authors. While this might not sound like much of an achievement to many, it is a huge success for the field of accelerator physics. "We gained energy of 12 kiloelectron volts. That is a 43 percent gain in energy," says Leon Bruckner, the paper's fourth author.

In order to accelerate the particles over such large distances (when seen from the nano scale), the FAU physicists combined the APF method with specially developed pillar-shaped geometrical structures.

This demonstration is just the beginning, however. Now the aim is to increase the gain in energy and electron current to such an extent that the particle accelerator on a chip is sufficient for applications in medicine. For this to be the case, the gain in energy would have to be increased by a factor of approximately 100.

"In order to achieve higher electron currents at higher energies at the output of the structure, we will have to expand the structures or place several channels next to each other," says Chlouba.

Head-to-head race among physicists
What the FAU laser physicists succeeded in doing was demonstrated almost simultaneously by colleagues at Stanford University in the United States; their results are currently under review.

The two teams are now working together on the realization of an "accelerator on a chip" in a project funded by the Gordon and Betty Moore Foundation.
