Precision measurements of intracluster light suggest possible link to dark matter

Faint light from rogue stars not bound to galaxies has been something of a mystery to scientists. The dimness of this intracluster light makes it difficult to measure, and no one knows how much there is. Scientists on the Dark Energy Survey, led by Fermilab, have made the most radially extended measurement of this light ever and have found new evidence that its distribution might point to the distribution of dark matter.

Engineers and scientists at Fermilab are designing machine learning programs for the lab’s accelerator complex. These algorithms will enable the laboratory to save energy, give accelerator operators better guidance on maintenance and system performance, and better inform the research timelines of scientists who use the accelerators. The pilot system will used on the Main Injector and Recycler, pictured here. It will eventually be extended to the entire accelerator chain. Photo: Reidar Hahn, Fermilab

Fermilab receives DOE funding to develop machine learning for particle accelerators

Fermilab scientists and engineers are developing a machine learning platform to help run Fermilab’s accelerator complex alongside a fast-response machine learning application for accelerating particle beams. The programs will work in tandem to boost efficiency and energy conservation in Fermilab accelerators.

Next-generation particle beam cooling experiment underway at Fermilab accelerator

High-intensity particle beams enable researchers to probe rare physics phenomena. A proposed technique called optical stochastic cooling could achieve brighter beams 10,000 times faster than current technology allows. A proof-of-principle experiment to demonstrate OSC has begun at Fermilab’s Integrable Optics Test Accelerator.

One minute with Kate Sienkiewicz, LBNF Near Site Conventional Facilities project manager

From working at the CIA to designing science facilities at Fermilab, Kate Sienkiewicz enjoys tackling complex problems. Currently, she oversees the team tasked with designing and building conventional facilities at the Long-Baseline Neutrino Facility near site for the international Deep Underground Neutrino Experiment — all with the overarching goal of understanding the universe.
