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
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.
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.
Researchers have found a way to convert nanoparticle-coated microscopic beads into lasers smaller than red blood cells. These microlasers, which convert infrared light into light at higher frequencies, are among the smallest continuously emitting lasers of their kind ever reported.
An international team led by scientists at Berkeley Lab and UC Berkeley discovered how to exploit defects in nanoscale and microscale diamonds and potentially enhance the sensitivity of magnetic resonance imaging and nuclear magnetic resonance systems while eliminating the need for their costly and bulky superconducting magnets.
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.
Berkeley Lab is offering a special tour to photographers on Wednesday, May 16, 2018, in a local event that is part of a Global Physics Photowalk 2018 competition. Follow @BerkeleyLab and #LBNLphotowalk online for updates on the local event.
A team at Berkeley Lab has designed, built, and delivered a unique version of a device, called an injector gun, that can produce a steady stream of these electron bunches. The gun will be used to produce brilliant X-ray laser pulses at a rapid-fire rate of up to 1 million per second.
In quantum materials, periodic stripe patterns can be formed by electrons coupled with lattice distortions. To capture the extremely fast dynamics of how such atomic-scale stripes melt and form, Berkeley Lab scientists used femtosecond-scale laser pulses at terahertz frequencies. Along the way, they found some unexpected behavior.
