Scientists Piece Together the Largest U.S.-Based Dark Matter Experiment
Upper (left) and lower photomultiplier tube arrays are prepared for LZ at the Sanford Underground
Research Facility in Lead, South Dakota. (Credit: Matt Kapust/SURF) Most of the remaining
components needed to fully assemble an underground dark matter-search experiment called
LUX-ZEPLIN (LZ) arrived at the project’s South Dakota home during a rush of deliveries in June.
When complete, LZ will be the largest, most sensitive U.S.-based experiment yet that is designed
to directly detect dark matter particles. -
The Physics Division hosted its thirteenth
“Physics in and Through Cosmology”
workshop for high school physics teachers
and students, June 24-28, 2019, at Berkeley Lab.
The workshop was designed for Physics teachers
and highly motivated high school students with an
interest in science, technology, engineering and
mathematics. Thirty-eight students and twelve
teachers from throughout the Bay Area participated
in the five-day workshop.The Physics Division hosted its thirteenth

A New Filter to Better Map the Dark Universe
Just as a wine glass distorts an image showing temperature fluctuations
in the cosmic microwave background in this photo illustration, large objects
like galaxy clusters and galaxies can similarly distort this light to produce lensing effects. -

The Simons Observatory, a Berkeley Lab-involved project under construction in Chile’s
Atacama Desert that will measure the properties of universe’s early light – the cosmic
microwave background (CMB) – with extreme precision, has received a new commitment of
$20 million from the Simons Foundation. -
Junsong Lin, an affiliate in Berkeley Lab’s Physics
Division and UC Berkeley postdoctoral researcher,
holds components of a low-mass dark matter detector
that is now in development. The search for dark matter
is expanding. And going small. While dark matter abounds
in the universe – it is by far the most common form
of matter, making up about 85 percent of the universe’s
total – it also hides in plain sight. We don’t yet
know what it’s made of, though we can witness its
gravitational pull on known matter.What if Dark Matter is Lighter?

The ‘Little’ Computer Cluster That Could
The PDSF computer cluster in 2003. Decades before
“big data” and “the cloud” were a part of our everyday
lives and conversations, a custom computer cluster
based at the Department of Energy’s Lawrence Berkeley
National Laboratory (Berkeley Lab) enabled physicists
around the world to remotely and simultaneously analyze
and visualize data. The Parallel Distributed Systems
Facility (PDSF) cluster, which had served as a steady
workhorse in supporting groundbreaking and even
Nobel-winning research around the world since the 1990s,
switched off last month. During its lifetime the cluster
and its dedicated support team racked up
many computing achievements -

Two scientists at Lawrence Berkeley National Laboratory (Berkeley Lab) have been selected by the U.S. Department
of Energy’s Office of Science to receive significant funding for research through its Early Career Research Program. The program,
now in its tenth year, is designed to bolster the nation’s scientific workforce by providing support to exceptional
researchers during the crucial early career years, when many scientists do their most formative work.
Our Mission:
To conduct a leading program of research in particle physics and cosmology through innovation in instrumentation, computing and theory.
