Acclaimed physicist to join Fermilab and NIU

Swapan Chattopadhyay

This fall Fermilab has the honor of welcoming internationally renowned physicist Swapan Chattopadhyay in a joint appointment with Northern Illinois University. Chattopadhyay's accomplishments span the realm of particle physics, but his forte lies in accelerator science and technology — a specialty from which both members of the appointment hope to benefit.

Currently serving as the director of UK's Cockcroft Institute, Chattopadhyay will join Fermilab's senior leadership team and will assist the accelerator research team labwide, working on a variety of advanced research projects. At NIU he will be a distinguished professor and serve as director of accelerator research.

Fermilab Director Nigel Lockyer noted that Chattopadhyay's expertise would help the laboratory align with the recently released P5 report.

"Swapan will be a crucial component to Fermilab's efforts to fulfill its part of the P5 vision for the future of particle physics," Lockyer said. "We are very excited to have him on our team."

Accelerator Division Head Sergei Nagaitsev agrees.

"As a joint NIU-Fermilab appointee, Swapan is an excellent addition to our accelerator research team," Nagaitsev said. "This is a unique opportunity for Fermilab to further its research goals and its presence in the accelerator and beam physics sciences."

In Chattopadhyay's decades of experience, he has fulfilled leadership roles in accelerator physics at University of California, Berkeley, at Lawrence Berkeley National Laboratory, where he founded and directed the Center for Beam Physics Berkeley, and Jefferson Lab, where he served as associate laboratory director for accelerators.

"With his help, we hope to establish a very strong enterprise that aligns with the Fermilab vision," said Vladimir Shiltsev, head of Fermilab's Accelerator Physics Center.

For the past seven years, Chattopadhyay served as the inaugural director of the UK-based Cockcroft Institute of Accelerator Science and Technology and as Sir John Cockcroft chair of physics at the universities of Liverpool, Manchester and Lancaster, where he sparked major advances in accelerator sciences, promoted critical collaborations with CERN and other global laboratories and, ultimately, helped establish the Cockcroft Institute as an internationally distinguished leader in accelerator physics.

"With its unique accelerator test facilities and a world-class skills base, Fermilab has the distinction of being the sole institution in the United States responsible for the nation's stewardship of the field of high-energy physics in the global context," Chattopadhyay said.

Scientists in the Accelerator Division and Accelerator Physics Center plan to work with Chattopadhyay to invent, implement and explore new, powerful and effective accelerator-based programs.

"It feels genuinely gratifying to be desired by the lab and I am honored to receive such warm welcome from my colleagues and leadership at Fermilab," Chattopadhyay said. "It is now time to dedicate myself to research that advances this great institution and serve the scientific community to secure the next high-energy physics facilities."

KEK: 50 years from the discovery of 'CP-violation'

From Interactions.org, July 11, 2014

In 1993 the SLAC National Accelerator Laboratory in California and the KEK laboratory near Tokyo in Japan embarked on a quest to understand the nature of CP violation, a tiny difference between matter and antimatter that is vital for our existence. This effect was discovered in the decay of a particle called a kaon in 1964. These kaons exhibited strange behaviour compared with other particles studied at the time, and we now refer to the quark that causes that behaviour as a strange (or just s) quark. The amount of CP violation in kaon decays is insufficient to explain how the universe came to be dominated by matter.

Learning the lay of the lab

Joe Lykken

When I first arrived at Fermilab as a wide-eyed, wet-eared associate scientist 25 years ago, my experience was mostly limited to working on the more mathematical end of particle physics. Over time, mostly from chatting with other Fermilab scientists, I started to gain an appreciation for the challenges and excitement of working on experiments. This led me to get involved with Tevatron physics and eventually to join the CMS collaboration two years before the turn-on of the Large Hadron Collider.

Every time one of my neighbors asks me about what's up at "Fermi," I feel proud to be to be part of one of the world's great scientific laboratories. As I start in my new role as deputy director, the science prospects for Fermilab have never been more exciting. The P5 report has given U.S. high-energy physics a big boost, and I am confident that at Fermilab we will do our part to move ahead.

Just last week, the Mu2e project passed the important DOE milestone called CD-3a, allowing us to move forward with long-lead procurement for the experiment. This achievement reflects excellent work by the Mu2e project team and many others at Fermilab.

Of course a laboratory is made great not by a bunch of buildings and equipment, but rather by people. In our case, we are about 1,800 employees and another 4,000 people who use Fermilab's experiments, computers and expertise, working together to do amazing science. Many of you are already old friends, but I look forward to getting to know everyone and learning from you how this lab really works and how to make it even better. My phone extension is 8422 and my email is lykken@fnal.gov. Don't be shy.

Mysterious X-rays might hint at dark matter

From Sky and Telescope, July 8, 2014

On February 10, 2014, Esra Bulbul (Harvard-Smithsonian Center for Astrophysics and NASA Goddard) and colleagues announced an odd discovery: long-exposure observations of galaxy clusters revealed a spike in emission at a particular X-ray energy, and Bulbul's team couldn't explain why.

Just four days later, another team led by Alexey Boyarsky (Leiden University, The Netherlands) posted the same result using independent methods and different observations.

Even before the Astrophysical Journal published Bulbul's initial results, papers flooded the arXiv online preprint repository (71 to date) serving up various theories to explain the source of the mysterious X-ray spectral line. Nearly all of them turned to dark matter. But is it really the answer?
