Summer school will nurture
new neutrino scientists

Neutrino Physics Summer School poster

As neutrino research at Fermilab progresses in the coming decades, attracting more physicists dedicated to the field is key.

This summer, from July 2-13, Fermilab and KEK will sponsor the Neutrino Physics Summer School, here at Fermilab. So far more than 50 international students have registered.

"We hope this meeting builds strong ties that will last throughout careers. Sometimes the people you meet at a summer school become friends and colleagues for life," said event co-organizer Gina Rameika of Fermilab's Neutrino Department.

The Neutrino Physics Summer School is aimed at senior graduate students and recent PhDs who study particle physics. Ten days of lectures and discussions are planned, lasting from 9 a.m. to 8 p.m. every day.

"After the lectures, the discussion sessions will have other physicists come in and explain the material further," Rameika said. "Some tough topics will be taught. We don't want people getting lost in the material early on, so we will guide them through it."

Organizers will keep the number of students small to encourage more personal interactions. Class topics range from the Standard Model to neutrino oscillations and decay, from both theoretical and experimental approaches.

Tuition and room and board will cost about $800, Rameika said, adding that it is hoped that a student's institution will cover the costs, however a small amount of scholarship funds will be available. Registration ends May 25, and about 20 seats remain.

Bruce Winstein returns as Panofsky Prize winner

Bruce Winstein

Bruce Winstein, 2007 Panofsky Prize winner and Samuel Allison Distinguished Service Professor in Physics at the University of Chicago, is anticipating a reunion in addition to his talk on Wednesday, June 6 at the Users' Annual Meeting.

"It will be a way to reach old colleagues I've lost touch with after I stopped doing so much experimental work at Fermilab," said Winstein, whose close Fermilab connection spanned more than 25 years from 1973 to 1999. A member of the National Academy of Sciences, Winstein had completed his undergraduate degree at UCLA and his PhD at Caltech.

Winstein's Panofsky Prize cites him for "leadership in the series of experiments that resulted in a multitude of precision measurements of properties of neutral K mesons, most notably the discovery of direct CP violation." He shared the Panofsky Prize with CERN's Heinrich Wahl and INFN's Italo Mannelli, who had worked on similar experiments. The researchers showed that weak forces directly violate CP symmetry. Winstein led the KTeV collaboration at Fermilab, which in 1999 announced the observation of direct CP (charge-parity) violation, critical in understanding the predominance of matter over antimatter in the formation of the universe.

Winstein then took a sabbatical at Princeton, where he evolved into a cosmologist. Returning to the University of Chicago, he initiated the National Science Foundation Center for Cosmological Physics. There, Winstein's current work on the cosmic microwave background radiation investigates the physical conditions in the early universe. He still thinks of himself as a particle physicist because: "particle physics and cosmology are overlapping more and more."

"My only regret is that he's no longer closely involved in the accelerator program at Fermilab," said Bob Tschirhart, Fermilab's ILC physics coordinator and associate head of the computer division. He worked with Winstein for more than 10 years. "He has high intellectual standards and is a continual source of new ideas. It's a powerful combination."

The Users' Meeting runs June 6-7. Users are encouraged to register. The complete program for the Users' Meeting is available here.

A Tale of Two Exoplanets: One Incredibly Hot, the Other Extremely Windy

New studies of two exoplanets find that one keeps its hot side excruciatingly hot and the other may be stirred by 5,000 mph winds.

New temperature measurements are revealing extreme behavior in two planets outside our solar system, called exoplanets. One study indicates that HD 149026 b-a relatively small but extremely dense planet orbiting a distant star-has an atmospheric temperature of 2,300 kelvins (about 3,700 degrees Fahrenheit), or twice that of the hottest previously studied planet.

Astronomers have also mapped the surface temperature of one of those next-to-hottest planets, the larger and less dense HD 189733 b. They conclude that winds are evening out its day and night temperatures by stirring together hot and cold gas.

Multilab team sets the stage
for LHC inner triplet repairs

The cold mass of the Q1 magnet (blue) and two of the four cartridges (red) that get attached to the cold mass and the vacuum vessel surrounding the magnet (not shown) with brackets.

Scientists and engineers from CERN, Fermilab, Lawrence Berkeley National Laboratory and Japan's KEK Laboratory are preparing for repairs of 18 sets of structural supports to Fermilab-built quadrupole magnets for the LHC accelerator under construction at CERN. On Tuesday, March 27, the structural supports to one quadrupole magnet, part of an "inner triplet" of three magnets named Q1, Q2, Q3, failed a high-pressure test in the LHC tunnel. Fermilab assembled nine inner triplets for the LHC, including one spare. They are used to focus the proton beams of the particle collider before they enter the four interaction points along the ring.

To fix the structural supports' design flaw, the team of scientists and engineers has proposed to add to each Q1 magnet and each Q3 magnet a set of four cartridges that can absorb the longitudinal force generated during the pressure test. The solution was presented to a team of experts during a review at CERN on April 24 and 25. Since then the design of the cartridge system has been refined and parts needed for the cartridges and their installation have been ordered. Detailed tests of the design are in progress. The final design reviews will take place at Fermilab and CERN over the next couple of weeks.

Software workshop reviews entire chain of data analysis

Group photo of the ILC Software Workshop, in front of LAL entrance

Even the best detector will be useless without clever reconstruction algorithms and software. On 2-4 May 2007, the ILC Software Workshop was held at LAL, Orsay (France). The whole chain of data processing was reviewed there: software framework and tools, algorithms and physics results. At the end of the workshop, DESY physicist Ties Behnke summarised that significant progress has been achieved over the past year and important performance milestones are close to being reached, even though the community is still small. Cambridge physicist Mark Thomson, finished his contribution declaring he was now convinced that Particle Flow Algorithm (PFA) can meet the ILC performance goals at 500 GeV and 1 TeV.
