Recycler: Antiprotons Meet Electrons
On Saturday, July 9, members of the Recycler Department/Ecool Group circulated a beam of electrons together with a beam of antiprotons in Fermilab's Recycler storage ring. They observed for the first time the interactions between the electrons and the antiproton beam. The project members took advantage of small number of antiprotons (1.5E10) available for a study at that time.

Less than 48 hours later, accelerator experts conducted a second study, using a larger number of antiprotons (about 42E10). Beams of antiprotons and electrons were circulating together and traveling at the same speed, and beam experts think they may have observed the first signs of cooling of the antiproton beam, the reduction of the beam's emittance. Scientists will examine the results in more detail in the upcoming days, and Fermilab Today will report on their findings next week.

TeV Particle Astrophysics Conference July 13-15

The organizers of the TeV Particle Astrophysics Conference at Fermilab, July 13-15, hope to bring the connection between particle physics and astrophysics into focus in much greater detail. "The beautiful thing is that so many of these areas are connected. The workshop is a fantastic opportunity to show where they come together," said theoretical physicst and conference organizer Olga Mena Requejo.

"The main motivation for the workshop," said theoretical astrophysicist and fellow conference organizer Gianfranco Bertone, "is the results from several experiments, including some interesting data from air Cherenkov telescopes, which are making astronomical observations at unprecedented levels of energy and resolution." The conference will also present results from the Pierre Auger Observatory at the wine and cheese reception on Friday. Overall, the conference hopes to explore the implications of these new results and look ahead to further experimental exploration.

Registration for the conference is over, but all talks and certain events are open to members of the Fermilab community. Felix Aharonian of the Max Planck Institute will speak on "Astrophysics and Cosmology with TeV Gamma-Rays" at the Fermilab Colloquium on Wednesday at 4pm. Young physicists in the field will present their work on posters the following afternoon. "We hope to bring together all those people who are working within all of these different, but related areas," said Bertone. "Experimentalists, theorists, everyone." More information is available online.

Experts Explore Science's Unanswered Questions
WASHINGTON, D.C.--Experts from a variety of scientific fields gathered at AAAS headquarters yesterday to discuss some of most pressing unanswered questions in science. As part of the 125th anniversary of Science, published by AAAS, four symposia addressed everything from the nature of the universe to the meaning of consciousness.

Director's Corner

I have taken advantage while in Europe to establish connections and discuss future plans with various labs and agencies.

We have major common interests with CERN. The level of activity at CERN in preparations for the LHC is enormous. Between staff, users and contractors, some 5,000 to 6,000 people are on site daily. It was great to see the contributions of Fermilab to CMS and to the accelerator. Both ATLAS and CMS can be appreciated in their astonishing scale. They are taking shape, but are not yet buttoned up, so it is easy to walk around and appreciate how the major pieces are coming together. The pace in the completion of accelerator components is equally impressive and Director General Robert Aymar and the CERN team are determined to turn on the machine in mid-2007.

During my visit to DESY I met old friends and made new connections. We explored the various areas of common interest where we hope to have future collaborations. They include many aspects of super conducting RF R&D, ILC detector R&D, the operation of remote centers for global projects such as LHC and combined data analysis that might use Tevatron and HERA results. I was impressed by the extent of Fermilab's contributions to the Tesla Test Facility. My hosts made sure that I understood how much they have appreciated the collaboration over the years, especially given the difficult circumstances for Fermilab.

The Instituto Nazionale di Fisica Nucleare (INFN) has supported Italian institutions participating in projects in the US. The contributions of INFN have been legendary at both Fermilab and SLAC. I had the opportunity to meet with Roberto Petronzio, the President of INFN, to discuss our common interest in future collaboration, ranging from completion of the Tevatron Run II to neutrinos and liquid Argon R&D to superconducting RF technology and the development of the ILC. Dr. Petronzio is now also the chair of FALC (Funding Agencies for the Linear Collider), which is of great importance to the future of the ILC.

Accelerator Update
July 8 - July 11
- During this 72 hour period Operations established one store that combined with an existing store provided the experiments with approximately 50 hours and 7 minutes of luminosity
- LRF4 conditioning slow
- Pbar troubled with many problems, ending with a ground fault
- TeV quench during shot setup
- Recycler showed signs of electron cooling
