The T2K Experiment is Named a "Top 10 Breakthrough of 2011" by Physics World Magazine  
The Tokai-to-Kamioka (T2K) collaboration has recently been named seventh in a list of the top ten breakthroughs of 2011 by the "Physics World" magazine. Their experiment appears to have measured, for the first time, muon neutrinos changing into electron neutrinos. Chang Kee Jung is international co-spokesperson for the collaboration. Stony Brook has a strong team working on this experiment, including Clark McGrew, Peter Paul, Chiaki Yanagisawa, postdocs and students. Congratulations to all of them for this great recognition.

In the experiment, the T2K team generated a beam of muon neutrinos at the Japan Proton Accelerator Research Complex (J-PARC), located on the East coast of Japan in Tokai. They fired the neutrinos on a 295 kilometer trip underground, to the Super-Kamiokande detector in Kamioka, near the West coast of Japan. The experiment revealed that six muon neutrinos had changed into electron neutrinos. Data collection ran for 13 months until the March 2011 earthquake in eastern Japan caused damage to the accelerator complex at J-PARC. The experiment will continue when the instruments are restored.

End of Tevatron era  
Next Friday, Sept. 30, the Tevatron proton-antiproton at Fermi National Accelerator Laboratory near Chicago will close after 26 years of investigation of the structure of matter and fundamental forces at the energy frontier. Some of the most important fundamental discoveries of our time, such as finding the top quark and studying its properties, precision measurements of the electroweak bosons, and many new results on hadrons containing a bottom quark have been made at the CDF and DZero experiments at the Tevatron. These results helped to test and refine the Standard Model of particle physics and shape our understanding of matter, energy, space and time. The Tevatron research program also yielded countless achievements in detector, accelerator and computing technology. DZero has published about 380 papers so far. See more here.

Our High Energy Experimental group has played many leading roles in the DZero experiment. Most recently, results from DZero has been used to identify important constraints on the mass of the still-to-be-discovered Higgs boson. During the next few years the evaluation of the data will continue, with more results and publications to come.

Joining the Department: Joanna Kiryluk, Angela Kelly and Neelima Sehgal  
Angela Kelly has a Ph.D. in Science Education from Columbia University, and M.A. and Ed.M. degrees from Teacher's College, Columbia University. Her Ph.D. dissertation was about the availability of physics courses in New York City public high schools. She has extensive experience in secondary school (7-12) chemistry and physics teaching, including AP courses and courses to gifted and talented students. She has been recently promoted to Associate Professor (tenure track) in Science Education at Lehman College, CUNY. Previous to that she was Assistant Professor (tenure track) at the same institution since 2007. She will be 50% at the Center for Science and Mathematics Education (CESAME)and 50% at the Department, starting in fall 2011.
Joanna Kiryluk received her PhD from Warsaw University in 2000 working in the Spin Muon Collaboration (SMC) at CERN measuring the spin-dependent structure functions g1 of the proton and deuteron at low x and Q2. Following this, she was a postdoc at UCLA working on nucleon spin in the STAR experiment until 2004 at which point she continued her work on nucleon spin via a postdoc appointment at MIT. Since 2006, she has been a Physicist Project Scientist working at LBNL on neutrino physics with the ICE CUBE experiment. Within each of these varied experiences, she quickly established herself as a leader and demonstrated extraordinary flexibility in adapting to new scientific pursuits. She will come in the fall of this year.
Neelima Sehgal received her Ph.D. in 2008 from Rutgers University. During her Ph.D. she and her advisors produced an influential paper about the analysis of precision measurements of the microwave background radiation. Later she became a vital participant in the Atacama Cosmology Telescope (ACT) collaboration and she led the team that conducted simulations and evaluation of the data obtained by the collaboration. This project has already resulted in the discovery of several new high red-shift galaxy clusters, and refined our understanding of the dark energy that makes up a large fraction of the Universe. Neelima will start in the fall of 2012, and in the meantime she will be at Princeton University.

In memoriam: Michael Marx  
Michael Marx passed away on August 2nd. Mike was a great colleague, an excellent teacher, an inventive and energetic researcher and administrator. Since 1980, when he joined Stony Brook University, he served the Department and the University in many capacities, most lately as Associate Vice President for Brookhaven Affairs. In the early 1980's he was active in the development of BNL's Isabelle collider. Later he led one of the working groups in designing experiments for the Superconducting Supercollider. He worked at the D0 experiment at Fermilab and acted as Deputy Project Director of the PHENIX experiment at the Relativistic Heavy Ion Collider, and he was manager/organizer of the KOPIO and MARIACHI projects. He was Associate Dean in the Colleege of Arts and Sciences, and President of the Arts and Sciences Senate.

An account has been set up at the Stony Brook Foundation for donations in Mike's memory. In accordance with his wishes, the proceeds of the account will be used to offer fellowships to graduate students moving into research that involve collaboration with Brookhaven National Laboratory.

John S. Toll  
John S. Toll, the second president of Stony Brook University, passed away.

After serving in the Navy in World war II and receiving Ph.D. in Physics in Princeton in 1952, he moved to the University of Maryland, where he was chair of the Department of Physics and Astronomy from 1953 to 1965. During his tenure as the President of Stony Brook University from 1965 to 1978, he led the drive to turn a small liberal arts college into the internationally recognized research University that we are today. He than returned to University of Maryland where he was an equally successful President and the first Chancellor of new University System of Maryland, until 1989. From 1989 to 1994 he was the President of the Universities Research Association (URA), a consortium of universities interested in experimental high energy physics that is currently the primary contractor for Fermilab. He was President of Washington College from 1995 to 2004.

Retirement of Professor James Lukens  
Professor Lukens will retire at the end of this summer. He came to Stony Brook in 1971 from Cornell University. Shortly after his arrival he established a laboratory for low temperature studies of novel phenomena in solids, including an advanced facility for fabrication of superconductor integrated circuits, that served as a key to his successful and growing research program for many years. Jim's primary interest is in macroscopic quantum phenomena and, in particular, the Josephson effect. In 1983, his group verified the fundamental relationship between the Josephson radiation frequency and voltage with an unprecedented, and still unsurpassed accuracy. In 1985, they were the first team to get reliable quantitative data on the effect of dissipative environment on macroscopic quantum tunneling. And Jim's most cited paper, published in 2000, reports the first experimental observation of quantum coherence in a macroscopic system. In this experiment the macroscopic current in a superconducting ring (as many as a billion of Cooper pairs) circulated neither clockwise nor counterclockwise, but is a superposition of the two possibilities, just as Schroedinger's cat is neither alive nor dead, but it is in a superposition of the two states.

Though Jim's interests are mostly in fundamental physics, he has achieved several results of significant practical importance. In the early 1980s, his group achieved reliable phase locking of Josephson oscillations in large junction arrays, thus opening a way to practical sources of coherent sub-THz radiation. In 1994, they demonstrated a single-electron trap (essentially the prototype of future "ultimate" single-electron memories) capable of holding an electron for hours. In 1998 they implemented and tested (in collaboration with Kostya Likharev's team) a superconductor digital circuit operating beyond 750 GHz. This was - and still is - the absolute record for computing speed.

We congratulate Professor Lukens, his students, postdocs and research staff for all of the achievements reached in his 40 years of tenure in Stony Brook.
