Compact

The USA has only two accelerators that can produce 10 billion electron-volt particle beams, and they're each about 1.9 miles long. "We can now reach those energies in 10 cm," said the CEO of TAU Systems, which has built an ultra-compact accelerator.

Researchers at the Fraunhofer Institute for Applied Solid State Physics (IAF) have developed a lightweight, compact radar that can “see” through non-transparent materials and whiteout snow conditions.
