The newly upgraded particle accelerator at the DoE’s Stanford Linear Accelerator Center (SLAC) has produced its first X-rays. The Linac Coherent Light Source (LCLS) upgrade, called LCLS-II, can emit up to a million X-ray pulses per second (8,000 times more than the original) and an almost continuous beam 10,000 times brighter than its predecessor.
its first X-rays. The Linac Coherent Light Source upgrade, LCLS-II, can emit up to a million X-ray pulses per second and an almost continuous beam 10,000 times brighter than its predecessor. Researchers believe it will enable unprecedented research into “atomic-scale, ultrafast phenomena” and shed new light on quantum computing, communications, clean energy and medicine.
One of the keys to the accelerator’s powerful upgrade is its cooling abilities. The original LCLS, which went online in 2009, was capped at 120 pulses per second because of the natural limits of how many electrons could simultaneously travel through the accelerator’s room-temperature copper pipes. But the updated version includes 37 cryogenic modules cooled to negative 456 degrees Fahrenheit , allowing it to “boost electrons to high energies with nearly zero energy loss.
SLAC researchers say the new capabilities will allow them to examine details of quantum materials with unprecedented resolution while enabling new forms of quantum computing and “reveal unpredictable and fleeting chemical events” to help advance clean energy tech. In addition, they say it could help scientists develop new pharmaceuticals by studying how biological molecules work on an unprecedented scale.
“Experiments in each of these areas are set to begin in the coming weeks and months, attracting thousands of researchers from across the nation and around the world,” said LCLS Director Mike Dunne. “DOE user facilities such as LCLS are provided at no cost to the users — we select on the basis of the most important and impactful science. LCLS-II is going to drive a revolution across many academic and industrial sectors.

Adriatic Metals to start output at Bosnia silver mine in NovemberBritish-based mineral exploration company Adriatic Metals plans to start production at its Vares Silver Project in central Bosnia in November, the first mine to open in Europe in over a decade, its CEO Paul Cronin said in an interview on Monday. Around 800 000 t of polymetallic ore will be dug annually from the mine, from which around 65 000 t of lead-silver concentrate and 90,000 tons of zinc concentrate is expected to be produced following the six-year exploration and a $200-million investment.

Solidarity questions if potential Kloof 4 layoffs are necessaryTrade union Solidarity is concerned about the fate of almost 3 000 Sibanye-Stillwater mineworkers whose jobs may be in jeopardy in the future, as the mining company considers the future of its Kloof 4 shaft, in Carletonville, South Africa. Sibanye last week announced that it would hold discussions with stakeholders to decide on the future of the gold mining operation, given the financial and operational challenges it is facing.
