Engineers at the Roque de los Muchachos Observatory have attached the EMIR spectrograph to the Gran Telescopio CANARIAS (GTC), realizing a more than decade long design and fabrication process. The cryogenic instrument was designed, built, assembled and verified entirely at the IAC (Astrophysics Institute of Canrias). It will produce images...

In May, Fermilab sent an electron beam with an energy of 50 million electronvolts, or MeV, through the photoinjector at the Fermilab Accelerator Science and Technology facility (FAST), achieving a major design goal for the accelerator and marking the beginning of a new accelerator science program at the laboratory.

The International Union of Pure and Applied Chemistry (IUPAC) has opened a five-month long public comment and review period of the names recommended for elements 113, 115, 117 and 118, the discoveries of which were announced late last year.

Researchers at the Department of Energy’s SLAC National Accelerator Laboratory, Stanford University and Louisiana State University have achieved a dramatic high harmonic generation (HHG) shift by shining an infrared laser through argon gas that’s been frozen at 20 K into a thin, fragile solid whose atoms barely cling to each...

An interdisciplinary team of scientists at the US Naval Research Laboratory (NRL) Electronics Science and Technology and Materials Science and Technology Divisions has demonstrated hyperthermal ion implantation (HyTII) as an effective means of substitutionally doping graphene—a hexagonally-arranged single-atomic thickness carbon sheet—with nitrogen atoms. The result is a low-defect film with...

Prototyping of a new, ultrasensitive “eye” for dark matter is making rapid progress at the Department of Energy’s SLAC National Accelerator Laboratory, according to researchers and engineers who have installed a small-scale version of the future LUX-ZEPLIN (LZ) detector to test, develop and troubleshoot various aspects of its technology. When...
