A new electron gun, designed and built at Berkeley Lab to supply electrons for a next-gen X-ray laser, fired its first electrons today. The X-ray laser is part of the LCLS-II project, which is an upgrade of SLAC National Accelerator Laboratory’s Linac Coherent Light Source X-ray laser.
In recognition of the International Day of Light (@IDL2019) on May 16, the Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab) is highlighting how scientists use light in laboratory experiments. From nanolasers and X-ray beams to artificial photosynthesis and optical electronics, Berkeley Lab researchers tap into light’s many properties to drive a range of
New data from the STAR experiment at the Relativistic Heavy Ion Collider (RHIC) add detail – and complexity – to an intriguing puzzle that scientists have been seeking to solve: how the building blocks that make up a proton contribute to its spin.
Combining a first laser pulse to heat up and “drill” through a plasma, and another to accelerate electrons to incredibly high energies in just tens of centimeters, scientists have nearly doubled the previous record for laser-driven particle acceleration at Berkeley Lab’s BELLA Center.
For several decades, the nuclear science community has been calling for a new type of particle collider to pursue – in the words of one report – “a new experimental quest to study the glue that binds us all.” This glue is responsible for most of the visible universe’s matter and mass. To learn about this glue, scientists are proposing a unique, high-energy collider that smashes accelerated electrons, which carry a negative charge, into charged atomic nuclei or protons, which carry a positive charge.
To help foster the broad applicability of high-intensity lasers, Berkeley Lab is a partner in a new research network called LaserNetUS. The network will provide U.S. scientists increased access to the unique high-intensity laser facilities at the Lab’s BELLA Center and at eight other institutions.
The Advanced Light Source (ALS), a scientific user facility at Berkeley Lab, has received federal approval to proceed with preliminary design, planning and R&D work for a major upgrade project that will boost the brightness of its X-ray beams at least a hundredfold. The upgrade will give the ALS, which this year celebrates its 25th anniversary, brighter beams with a more ordered structure – like evenly spaced ripples in a pond – that will better reveal nanoscale details in complex chemical reactions and in new materials, expanding the envelope for scientific exploration.
Lawrence Berkeley National Laboratory (Berkeley Lab) this week announced support from the Department of Energy that significantly expands Berkeley Lab’s research efforts in quantum information science, an area of research that harnesses the phenomenon of quantum coherence, in which two or more particles are so tightly entangled that a change to one simultaneously affects the other. Quantum information science seeks to utilize this phenomenon to hold, transmit, and process information.
The world’s cutting-edge particle accelerators are pushing the extremes in high-brightness beams and ultrashort pulses to explore matter in new ways. To optimize their performance – and to prepare for next-generation facilities that will push these extremes further – scientists have devised a new tool that can measure how bright these beams are, even for pulses that last only quadrillionths or even quintillionths of a second.
A new study calls for the U.S. to step up its laser R&D efforts to better compete with major overseas efforts to build large, high-power laser systems, and notes progress and milestones at the BELLA Center at the Department of Energy’s Berkeley Lab, and other sites.
