Don’t forget that Wednesday is Fermilab's Daughters and Sons to Work day.

Fermilab’s DASTOW program returns with traditional favorite activities including Mr. Freeze’s cryogenics show, a trip to see the bison, the FUNdamentals of Physics show and a demonstration of skills and safety at the Fermilab Fire Department.

For a complete schedule of events and to see photos from previous DASTOW events, visit the DASTOW Web page.

New average integrated luminosity record

Between June 13 and June 20 the Tevatron reached a new average integrated luminosity record for a single calendar week. The new record, 78.4 inverse picobarns, replaces the previous record of 76.5 inverse picobarns, which was set during the week of May 2, 2011.

Alvin Tollestrup receives IEEE superconductivity award

Alvin Tollestrup

Alvin Tollestrup came to Fermilab in 1975 for what was supposed to be a six-month sabbatical. He has now been at Fermilab for more than 35 years, and at age 87, is still making strides for the field of high-energy physics.

This year, he has been selected to receive the IEEE Council on Superconductivity Award for Significant and Sustained Contributions to Applied Superconductivity. Tollestrup was chosen as one of three recipients of the 2011 award for his many contributions in high-energy physics and to particle accelerators, said Martin Nisenoff, chair of the awards committee for the IEEE Council on Superconductivity.

Tollestrup led the pioneering work of designing and testing 1,000 superconducting magnets used in the Tevatron. This was the first large-scale application of superconductivity.

“The Tevatron was the premiere accelerator in the world and many discoveries have come out of it, so it was a very major accomplishment that Alvin should be recognized for,” Nisenoff said.

Tollestrup is also being recognized for his more recent work on the development of stronger superconducting magnets for application in the proposed muon collider. The goal of the research is to develop high-temperature superconducting materials to make magnets several times stronger than what is currently possible. Tollestrup is a co-principal investigator for this multi-institutional collaboration funded by the American Recovery and Reinvestment Act. He serves with David Larbalestier, from the National High Magnetic Field Laboratory at Florida State University.

Tollestrup said one of the most rewarding components of his work has been to see the far-reaching applications of superconducting magnets in other fields of science, including chemistry, biology and medicine.

He was surprised to learn he had been selected for the award and is grateful to the IEEE for supporting the field of high-energy physics. He will receive the award on Sept. 12 at the 22nd Magnet Technology Conference in Marseille, France.

First results from Japanese neutrino experiment hint at big things to come

From Science Now, June 15, 2011

The headlines were certainly dramatic. "Unlocking the Mysteries of Antimatter" read one, "Japanese Neutrino Find Could Explain Why There is Matter in the Universe" proclaimed another. The truth is somewhat less momentous yet nonetheless exciting for particle physicists. Scientists working with a massive subterranean particle detector in Japan have directly observed a hoped-for phenomenon in which particles called muon neutrinos transform into others called electron neutrinos.

In itself, that preliminary observation tells physicists nothing new about the relationship between matter and antimatter. However, the effect appears to be so large that it suggests future experiments now in the planning may have a far easier time spotting other phenomena. That includes a possible asymmetry between the behavior of neutrinos and antineutrinos that could explain why the universe evolved to contain so much matter and so little antimatter.

"If this result holds up, it would mean that we've got kind of a fun decade ahead of us in neutrino physics," says Mark Messier, a physicist at Indiana University, Bloomington, and co-spokesperson for the NOνA neutrino experiment at Fermi National Accelerator Laboratory in Batavia, Illinois.

An important result

Fermilab Director Pier Oddone

Last week the T2K Collaboration in Japan announced the observation of electron neutrino appearance events using the neutrino beam from J-PARC to the Super Kamiokande detector (Read paper submitted to Physical Review Letters). The collaboration reported the observation of six events with an expected background of 1.5 ± 0.3 events. The probability that the background would fluctuate upward to give six events is less than 1 percent. Thus we now have strong evidence that muon neutrinos oscillate to electron neutrinos and that the last unknown neutrino mixing angle, called theta-13, which tells us about these oscillations is relatively large. That this parameter should be relatively large is important because it will enable a rich future program of neutrino oscillation experiments, in particular experiments that will be able to make statements about matter-antimatter asymmetry in the universe. This measurement is a great achievement for our colleagues at J-PARC and T2K.

The earthquake and tsunami stopped operations at T2K and J-PARC in March, but our Japanese colleagues expect to be back up and running by the end of this year. Once J-PARC is restored to working order, the number of protons on target will ramp up quickly and the results after a year of running will be considerably more precise. In the meantime the MINOS experiment will update its 2010 constraints on theta-13 and several reactor neutrino experiments could confirm the T2K results within a year or two. NOvA will be able to measure theta-13 accurately once it is up and running. This is also very good news for the Long Base Line Neutrino Experiment since the likely value of theta-13 is large enough for LBNE to achieve its full promised potential.

This week the working group established by Director of DOE’s Office of Science Bill Brinkman to develop options for the Homestake site where the far LBNE detector would be placed will present its report to HEPAP. This report will be used by the DOE to decide how to proceed. Later in the month a National Research Council committee chaired by Andy Lankford will report on the value of the science proposed for the Deep Underground Laboratory at the Homestake site. So all the pieces are gradually falling into place for the DOE to make a decision on Homestake and on LBNE.
