Project X, P5-report alignment focus of third workshop

Fermilab scientists Sergei Nagaitsev and Dave McGinnis speak with Fermilab Deputy Director Young-Kee Kim during a break at the Second Workshop on Physics with a high-intensity proton source in January.

Researchers will gather this week to flesh out experiments to keep Fermilab vital and aligned with the recently released Particle Physics Project Prioritization Panel roadmap for the next decade.

"The workshop will immediately follow the Fermilab Annual Users' Meeting. Many of the talks at the Users' Meeting will be relevant to Project X and the future Fermilab program, so we are hopeful that users will participate in both meetings," said Kevin Pitts, chairman of the Fermilab Users' Executive Committee.

The third Workshop on Physics with a high-intensity proton source begins with a town meeting in One West Thursday at 6 p.m. with Charley Baltay from Yale University, who chaired the P5, Dennis Kovar from DOE, Joe Dehmer from NSF, and Pier Oddone. The workshop continues on Friday with a series of talks given by the leaders of the proposed experiments.

"The second workshop in January focused on the details of the experiments proposed to take advantage of a high-intensity proton source, their physics impact and the development of the overall experimental strategy. The results of the second workshop and the physics document 'Golden Book' were presented at the first P5 meeting at Fermilab on Jan. 31 - Feb. 2, and were included in the P5 process in developing the roadmap," said Fermilab Deputy Director Young-Kee Kim. "With the P5 roadmap released, this time we will focus on understanding P5's roadmap and the implication of P5's recommendations in detail, and developing short- and long-term experimental strategies that are aligned with P5's recommendations.

View the preliminary program and registration. There is no registration fee.

The two previous workshops drew large, enthusiastic crowds from more than 78 institutions. Following the recommendations of the Fermilab Steering Group Report released in 2007, these two workshops focused on physics that is unique and is complementary to the LHC in the next decade.

"The early parts of this plan might include proposals for experiments that can run relatively soon as well as R&D plans for experiments that are on a longer timeline," Pitts said.

URA selects two winners of 11th thesis competition

The URA Thesis Award Committee reads thousands of pages of dissertations to determine that year's best submitted thesis.

But, this year after reading 17 thesis submissions of more than 200 pages each, the committee chose two winners out of a strong field. Awards will go to both Ryan Patterson, a graduate student at Princeton University who now works on MINOS and NOvA at CalTech, and Peter Wagner, a graduate student from Texas A&M University who is now at the University of Pennsylvania working on ATLAS.

"This year's selection was difficult," said Rick Tesarek, URA Thesis Committee chair. "We had the most submissions in the 11-year history of the award, and they were all of an exceptional quality. These two stood out for both their interesting topics and strong contributions to furthering Fermilab science."

Ryan Patterson

Patterson's dissertation, "Search for Muon Neutrino to Electron Neutrino Oscillations at Delta M Squared > 0.1 eV Squared" focuses on the non-observation that muon neutrinos do not oscillate into electron neutrinos in a given mass range. This result was named among the top science results of 2007 by the American Institute of Physics. According to Tesarek, Patterson also developed a lot of new techniques to obtain the MiniBooNE results.

Peter Wagner

Wagner's thesis, titled "Search for Heavy, Long-Lived Particles that Decay to Photons," focused on searching for different types of interactions not described by the Standard Model. While his search is off the beaten path, Tesarek said, it has had high interest for theorists, because Wagner is searching for what should not exist. Wagner's work also included development of reconstruction techniques and implementation of a new system for CDF. Data in his thesis used the instrumentation he worked on.

This year's winners will split a $3,500 prize funded by the Universities Research Association. Both Patterson and Wagner will receive their awards on Wednesday, June 4, as part of the annual Users' Meeting. They will also give brief talks after the award presentation about their thesis research.

Optics crucial to achieve
long-term vision for LHC

Giorgio Apollinari, head of the Technical Division, wrote this week's column.

Giorgio Apollinari

One of the elements of Fermilab's vision for the future, highlighted by last week's P5 report to HEPAP, is the continued exploitation of physics opportunities at the Large Hadron Collider through our participation in the luminosity upgrades of the accelerator.

Higher luminosity requires magnets with stronger magnetic fields. For this purpose, several laboratories in the United States are developing a new generation of superconducting magnets, based on niobium-tin (Nb3Sn), to push the performance beyond the level achieved by the niobium-titanium (NbTi) magnets presently used in the Tevatron and the LHC. Unfortunately, Nb3Sn is brittle and difficult to turn into magnet coils.

This difficulty motivated Fermilab scientists and engineers to give high priority to the quality control of the manufacturing process, the performance of the coils and, ultimately, the quality of the optics in the final magnets. Lack of any of these features could cloud even the most amazing technical achievements on the field strength.

Members of the TD High Field Magnet program work in conjunction with the U.S. LHC Accelerator Research Program to develop Nb3Sn magnets with good and reproducible field quality, excellent alignment properties, reliability and ease of manufacturing.

The Fermilab Nb3Sn program has produced 16 almost identical, 1-meter-long Nb3Sn dipole coils, making incremental improvements to the conductor and manufacturing technology. This is the largest set of identical coils and collared Nb3Sn magnets in the world and represents the most complete study of magnetic effects of such magnets. We found that, despite the increased coil complexity, the Nb3Sn magnet field errors are comparable to those of the NbTi counterparts. Most of the Nb3Sn coils show insignificant snap-back effects. Magnetic strips, carefully placed and embedded in the Nb3Sn magnets, can control the large magnetization effects that occur during the injection of particles into the ring.

The near-term goal of the LARP magnet collaboration is the construction and testing of a 3.6-meter-long focusing quadrupole magnet by the end of 2009, for a possible implementation of the LHC Phase 2 Upgrades in the second half of the next decade. The results of the Fermilab HFM program are crucial to the progress and success of the LARP program.
