Researchers at Cornell’s Center for Bright Beams, have developed a technique to create a photocathode – a material vital to the performance of some of the world’s most powerful particle accelerators – from a single-crystal alkali antimonides.
A collaboration of researchers led by Cornell has been awarded $22.5 million from the National Science Foundation (NSF) to continue gaining the fundamental understanding needed to transform the brightness of electron beams available to science, medicine and industry.
A team of scientists at the Center for Bright Beams – a National Science Foundation Science and Technology Center led by Cornell – are working on the next generation of superconducting materials that will greatly reduce the costs associated with operating large particle accelerators and lessen their environmental impact. The research could also make it easier for smaller institutions and industry to use these critical tools.
A single human cell contains thousands of proteins that perform a vast array of functions, from fighting off viruses to transcribing DNA. By understanding the structure of these proteins, researchers can interpret their functions and develop methods for turning them on and off.
Why should resources – financial or intellectual – be dedicated to the pursuit of theoretical knowledge when the world has so many pressing problems? On April 24 particle physicist Nima Arkani-Hamed will examine the significance of performing basic research in his latest public talk as an A.D. White Professor-at-Large. The talk will be held at 7:30 p.m. in Rockefeller Hall’s Schwartz Auditorium and is free and open to the public. A reception will follow at 9 p.m. at the West Pavilion of Clark Hall.
Teams of scientists, including researchers from the Cornell physics and astronomy departments, are collaborating on two of the largest telescopes ever built to take readings on the universe’s oldest light measurable, known as the Cosmic Microwave Background, or CMB.
These telescopes will be placed in the Atacama Desert of Northern Chile and will give scientists new tools to record the earliest signals from the universe.
