At a time when the Large Hadron Collider is scheduled to start up in 2007 and the Tevatron at Fermilab will shut down by the end of this decade, the particle physics program in the United States is at a crossroads. Should the United States fold its cards and determine that the field of particle physics has lost its steam? Or should the United States step up to the plate and prepare to submit a bid to host the next-generation particle accelerator? These are the questions that the National Academies’ National Research Council charged the Committee on Elementary Particle Physics in the 21st century (EPP2010) to answer, asking the 22-member panel to lay out a 15-year plan. Yesterday on 26 April in the National Academies’ Keck Center in Washington D.C., EPP2010 launched their much-anticipated report, "Revealing the Hidden Nature of Space and Time – Charting the Course for Elementary Particle Physics."

Using state-of-the-art technology, cryomodules are vessels that contain superconducting cavities in a linear accelerator. Inside the module, liquid helium cools the cavities to -271° C, only slightly warmer than the coldest possible temperature. The superconducting cavities operate at these super-cool temperatures, pumping more and more energy into the particles that are moving at nearly the speed of light inside the accelerator.

As the projected timeline currently stands for the International Linear Collider, the machine will start running in about a decade or so. While some physicists view retirement as a novel concept, ILC scientists and engineers must face the fact that the next-generation particle accelerator needs a next-generation of experts behind it. After the overwhelming response of applicants to the International Accelerator School for Linear Colliders, physicists can rest a little easier, knowing that a future generation of scientists is ready and eager to take the helm.

While figuring out how to smash electrons and positrons at an energy level of 500 GeV in a tunnel that is approximately 25 kilometers long could be considered a minor challenge, one of the largest hurdles for the International Linear Collider is developing accurate costing estimates. While at first estimating the cost of something might not sound that hard (some of us do it almost every day for groceries, house supplies, and of course shoes), there are a number of factors that will make costing an extremely complicated process for a global project like the ILC.

Approximately one year from now, the Global Design Effort expects to request proposals on a world-wide basis for siting the International Linear Collider. Although a long road remains to selecting a site for the ILC, facilitator Doug Sarno will tell you it is never too early to start public participation. In anticipation of submitting a proposal to host the ILC, Fermilab started discussions with local citizens, and two years ago, they established a Community Task Force on Public Participation. Ranging from a young high school student to a local mayor, the 22-member group developed a set of mutual expectations for how Fermilab will interact with the community on issues that effect them both. As the site selection for the ILC moves forward, the role of the Community Task Force will become increasingly important and perhaps even serve as a model on public participation for other regions involved in the global project.

With the projected timescale for the International Linear Collider, the majority of scientists and engineers who are currently working on the proposed project will be well into retirement by the time the first collisions occur. Uriel Nauenberg, a particle physicist at the University of Colorado, is doing his part to ensure that the field of particle physics will have a future generation to carry on the projects and experiments that are under development now.

On Monday, 6 February, a team of cryogenic engineers and accelerator physicists at Fermilab successfully cooled the first TESLA 9-cell 1.3 GHz cavity to 4.5 K (Kelvin) in the ILC Test Area in the Meson Detector Building (ILCTA-MDB). Travelling to Hamburg, Germany, Fermilab personnel assisted DESY in preparing the "ILC-like" cavity, called Capture Cavity II (CCII), and shipped it to its current home in Batavia, Illinois in August 2005.

Last November, a team of accelerator physicists from KEK and SLAC succeeded in extracting three bunches of electron beam each spaced by 154 nanoseconds from the storage ring in the Accelerator Test Facility (ATF) in Japan. (See ILC NewsLine, 10 November 2005) Using a "kicker magnet" with a pulse length of 310 nanoseconds, developed by SLAC, this important accomplishment delivered an ILC-like beam for the first time.

After more than two months of intensive work, the Curriculum Committee has selected a group of 21 lecturers from around the world to teach at the International Accelerator School for Linear Colliders. Scheduled for 19-27 May 2006, the school will take place at Sokendai, Graduate School for Advanced Studies in Hayama, Japan.

Last month in Boulder, Colorado, about 30 scientists shared ideas and worked together on software problems at the American Linear Collider Physics Group Detector Simulation Workshop.
