The Department is saddened by the passing of Prof. Bob March.
Tuesday, August 4, 2015
Prof. March, 81 years old, died peacefully at Agrace HospiceCare on August 4, 2015. Prof. March came to Wisconsin in 1960 as a post doc with Profs. Walker and Erwin. In 1962 he joined the faculty as an Assistant Professor, working with Profs. Camerini, Fry, Cline and Reeder on bubble chambers. March pioneered measurements of muon polarization in bubble chambers, which permitted the first direct test of time reversal invariance in weak interactions. His interests later in his career were in particle astrophysics. Prof. March was author of Physics for Poets, which has been translated into 6 foreign languages. Of his more than 240 publications, more than 100 were written for general audiences. He received many distinguished teaching awards during his tenure at Wisconsin.
In 2003 Prof. March wrote a history of the early years of Physics at Wisconsin (1848-1960) which can be found here.
All are welcome to join in a memorial and celebration of Bob’s life in the Varsity Room of Union South (on the UW Campus) on Sunday, September 13, 2015 at 1:30 PM.
John Unguris, Ph.D. 1980, wins APS 2015 Joseph F. Keithley Award for Advances in Measurement Science
Thursday, July 16, 2015
For the invention and development of electron spin sources and detectors, and their application to measurement science.
John Unguris received a B.S. in Physics from Carnegie Mellon University in 1973, and a Ph.D. in Physics from the University of Wisconsin in 1980. He initially joined the National Institute of Standards and Technology (NIST) as a National Research Council Postdoctoral Research Associate investigating the application of electron spin measurements to various surface sensitive spectroscopies. This work lead to the development of an electron microscopy technique for directly imaging magnetic nanostructures, Scanning Electron Microscopy with Polarization Analysis (SEMPA). He has since used SEMPA to measure the magnetic properties of a wide variety of structures including ultrathin patterned magnetic films, oscillatory exchange coupled magnetic multilayers, and multiferroic heterostructures. He is currently a Project Leader in the Electron Physics Group in the Center for Nanoscale Science and Technology, where he is leading multiple projects investigating the fundamental physics of magnetic nanostructures. He is a Fellow of the American Physical Society, and has been awarded a Bronze Medal from the Department of Commerce, and is a member of AVS and APS.
As the giant physics machine restarts, the essential role of UW in the LHC continues
Tuesday, July 14, 2015
UW-Madison has dozens of scientists — including graduate students and postdoctoral fellows — involved in the experiments, analysis, data handling and computation at the Large Hadron Collider. Research has resumed at the 27-mile tunnel on the Swiss-French border after two years spent raising its power. Pictured is Wesley Smith with a special-purpose data winnowing board built for the new, high-power runs at the Large Hadron Collider. Photo credit: David Tenenbaum, UW-Madison.
The Department of Physics participated in making Operation Military Kids University 2015 a success: http://www.news.wisc.edu/23844. Wonders of Physics student workers Emily Ehlerding and Jake Nesbit helped with hands-on demonstrations. Wisconsin 4-H Military Kids programs support the nearly 15,000 Wisconsin youth in military families.

UW Physics Students Rock the LHC
Tuesday, June 2, 2015
As the Large Hadron Colider nears data taking at a record 13 TeV, graduate students have some fun. Can you identify the two from UW?
Garage Physics launch and recover a high altitude ballon. Pictured are Brett Unks and undergraduates Bella Nasirudin and Catherine Tuanqui at the launch site, Governor Nelson Park in Middleton. The balloon was recovered in Edgerton after a couple hour flight. The payload featured a digital temperature logger, an Android phone running Justin Vandenbroucke’s cosmic ray detector app., an external camera, and a GPS unit. Also participating in the development were Asst. Prof. Justin Vandenbroucke, plant pathology graduate student Alex Biligri, and Physics graduate student Shaun Alsum.

The LHC is back in business, now ready for proton-proton collisions at a record 13 TeV
Sunday, April 5, 2015
After two years of intense maintenance and consolidation, and several months of preparation for restart, the Large Hadron Collider, the most powerful particle accelerator in the world, is back in operation. Today at 10.41am, a proton beam was back in the 27-kilometer ring, followed at 12.27pm by a second beam rotating in the opposite direction. These beams circulated at their injection energy of 450 GeV. Over the coming days, operators will check all systems before increasing energy of the beams.
High on a sleeping Mexican volcano, a new particle astrophysics observatory is about to blink to life, commencing an all-sky search for very high-energy gamma rays — a search that could greatly expand the catalog of known gamma ray sources and chip away at the mystery of the cosmic rays that constantly bombard our planet.
IceCube, the cubic kilometer, sub-polar detector that in 2013 gathered the first-ever evidence of cosmic neutrinos, is the star of particle astrophysics at the South Pole. Soon, however, a complementary detector known as the Askaryan Radio Array or ARA will join the hunt for the highest energy neutrinos.
