Atomic jet: First lens for extreme-ultraviolet light developed

Scientists have developed the first refractive lens that focuses extreme ultraviolet beams. Instead of using a glass lens, which is non-transparent in the extreme-ultraviolet region, the researchers have demonstrated a lens that is formed by a jet of atoms. The results provide novel opportunities for the imaging of biological samples on the shortest timescales.

New device widens light beams by 400 times

Scientists have now developed a highly efficient device that enlarges the diameter of a light beam by 400 times. Wider light beams have many applications, including boosting the speed and sensitivity of medical imaging and diagnostic procedures.

The future of fighting cancer: Zapping tumors in less than a second

New accelerator-based technology being developed by the Department of Energy's SLAC National Accelerator Laboratory and Stanford University aims to reduce the side effects of cancer radiation therapy by shrinking its duration from minutes to under a second. Built into future compact medical devices, technology developed for high-energy physics could also help make radiation therapy more accessible around the world.

Moscovium and Nihonium: FIONA measures the mass number of two superheavy elements

A team led by nuclear physicists at the Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) has reported the first direct measurements of the mass numbers for the nuclei of two superheavy elements: moscovium, which is element 115, and nihonium, element 113.

Hard limits on the postselectability of optical graph states

Since the discovery of quantum mechanics, in the early 20th century, physicists have relied on optics to test its fundamentals.

From turkeys to turn-keys

Last week, millions of Americans unwrapped a shrink-wrapped turkey for Thanksgiving. If so, they owe thanks to electron beams, which made the shrink-wrapping possible. But the electron beam can do a lot more: It can sterilize medical equipment, treat wastewater and print metal parts. Industrial accelerators that generate these electron beams are rapidly expanding. The Illinois Accelerator Research Center (IARC) is on a mission to build a high-power, compact, superconducting electron beam accelerator that will serve all of these purposes.

Scientists obtain a hexagonal modification of silicon

A team of scientists from Lobachevsky University (Nizhny Novgorod, Russia) has obtained a material with a new structure for applications in next-generation optoelectronics and photonics. This material is one of the hexagonal modifications of silicon, which have better radiative properties compared to conventional cubic silicon, which is traditionally used in microelectronics.

Neutron production at ORNL's SNS reaches design power level

The Spallation Neutron Source at the Department of Energy's Oak Ridge National Laboratory has broken a new record by ending its first neutron production cycle in fiscal year 2019 at its design power level of 1.4 megawatts.

NASA Awards Launch Range Operations Services Contract

NASA has awarded a contract to LJT and Associates Inc. of Columbia, Maryland, to provide launch range operations support at the agency’s Wallops Flight Facility in Wallops Island, Virginia.
