Lessons in Public Participation: ILC in the Neighborhood

| 2 March 2006 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.

Future Generation of Physicists at U. Colorado Helps with ILC

| 23 February 2006 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.

Following the Beam

| 23 February 2006 Obtaining high luminosity beams will be crucial for the future International Linear Collider. An important indication on the beam quality is given by the emittance which depends on its size and opening angle. The lower the emittance, the easier it is to focus the beam and the more particle collisions can occur and be analysed. In the GDE the "Accelerator physics" group, a special team dedicated to the technical systems organised at CERN, on 08-11 February 2006, a "Low Emittance Transport Workshop". About 30 accelerator scientists, coming from all regions, attended it. Category: Feature | Tagged:

Fermilab Cools First TESLA Cavity from DESY

| 16 February 2006 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.

TRIUMF Kicker Group Experiments with 6 Nanosecond Pulses

9 February 2006 The rise and fall times of the pulses in the injection kickers influence the minimum circumference of the damping rings in the International Linear Collider. The Baseline Configuration Document features 6 km rings which will require pulsers to feed 50 ohm stripline kickers. The 5 kV (kilovolt) pulses must have 6 ns (nanosecond) rise and fall times, and a total duration of approximately 14 ns. Operating in a burst mode, every 5 seconds the kicker will have a 3 MHz (megahertz) burst that lasts 1 ms (millisecond). The combination of the electric component from the 5 kV voltage pulse and the magnetic component from the accompanying 100 A (amp) current pulse will deflect the electron and positron beams. The temporal specification of the kicker pulse presents a challenge to the existing generation of pulser technology. Category: Feature | Tagged:

Europe Defines a Strategy Plan for the Future of Particle Physics

| 9 February 2006 Last week, the future of particle physics in Europe was debated in Orsay (near Paris, France) from 30 January to 1 February. An Open Symposium, organised by the CERN Council Strategy Group, gathered more than 400 scientists from all over Europe, as well as representatives from North America and Asia.

Lecturers Selected for International Accelerator School for Linear Colliders

| 2 February 2006 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. Category: Feature | Tagged:

Algorithms Flow at Detector Simulation Workshop

Review of the French ILC Detector R&D

| 26 January 2006 The French ILC community held a SOCLE meeting (Seminar Oriented towards a Contribution to an Electron Linear Collider) in Lyon on 12-13 January 2006. More than 70 participants attended a review of the ongoing ILC detector R&D effort in CNRS/IN2P3 and CEA/DAPNIA laboratories. Future prospects and organisation aspects were discussed. Software tools dedicated to physics analyses and detector optimisation were also debated, in preparation for the Detector Conceptual Report, which will be delivered to the GDE by the end of 2006.

Finding the nano-size beam

26 January 2006 The International Linear Collider (ILC) interaction region beam sizes and component position stability requirements will be as small as a few nanometers. Making a head-on collision with a few nanometers beams, each beam travelling across some 20 km in the linear accelerator, is a bit like colliding two baseballs -- one thrown from earth and the other from Saturn! It is important for the ongoing ILC design effort to demonstrate that these tolerances can be achieved -- ideally using a beam-based stability measurement. Category: Feature | Tagged: ,
