3D Printer and Off-the-Shelf Parts Help Build Self-Aligning Mirror Mechanism for ITER

At the Princeton Plasma Physics Laboratory, the spirit of tinkering lives. This past summer a team of engineers invented a mechanical device designed to be installed on ITER, the multinational fusion machine being built in the south of France, using 3D printing and parts bought at Walmart.

Radially Polarized Laser Beam Can Track Speeding Particles

It might be easier to track tiny particles in the future – even when they hurtle along with the speed of a rifle bullet. This is thanks to researchers working with Christoph Marquardt and Gerd Leuchs at the Max Planck Institute for the Science of Light, who have discovered that these particles can be tracked with a radially polarized laser beam. In radially polarized light, the oscillation planes of the light waves arrange themselves like the spokes of a wheel. When the researchers cause a particle to fly through such a laser beam, they are able to determine its position several billion times per second by measuring the polarization of the beam.
