A Director's Corner by Jenny List, new chair of the working group
Recently, Hitoshi Murayama has been appointed as chair of the next Particle Physics Project Prioritization Panel in the US, and therefore stepped down from his role as chair of the Physics and Detector Working Group of the International Development Team, also known as IDT-WG3. I would like to express my deep gratitude to Hitoshi for […]
Is the beam delivery system delivering? Ten years ago, at the Global Design Effort’s formative meeting in Snowmass, Colorado, ILC communicator Perrine Royole-Degieux interviewed Phil Burrows, then professor at Queen Mary University of London, about the beam delivery system. How has the home straight where the particle bunches get squeezed, focused and brought to collision, […]
Former GDE Director Barry Barish revisits the project he led for eight years
Many of the striking advances in particle physics during the particle collider era have resulted directly from the complementarity of hadron-hadron and electron-positron colliders. Unfortunately, it is not practical to build a complementary circular electron-positron collider for the LHC capable of reaching center-of-mass energies of about 1 TeV (tera electronvolt) because of the large amount of […]
The design is clunky, but the faces look familiar: the very first issue of NewsLine was published on 18 August 2005. It had lots of live coverage from the meeting in Snowmass that more or less officially started a global R&D project for the International Linear Collider. It made scientists from different collider and R&D […]
The P5 report was approved by the HEPAP meeting on May 22. As a new HEPAP member, I participated in discussions on the report, even though I had to call in from Japan. The news was already covered in the Director’s Corner by Harry Weerts and Mike Harrison. But I’d like to write about my […]
The US High Energy Physics (HEP) programme is presently guided by a roadmap put together in 2008 by US Department of Energy (DOE) High Energy Physics Advisory Panel (HEPAP). Since that time the global HEP situation has continued to evolve in regards to both the physics (most notably the Higgs boson) and international HEP planning […]
After last summer’s preparation for the European Strategy process – in the meantime successfully concluded into an approved document by the CERN Council – this summer has been dedicated to the Snowmass process in the US, as well as hectic ILC preparations and discussions in Japan. In all regions linear collider projects are high on […]
From the output of the “Snowmass” meeting, US particle physicists will chart a path to answering some of science’s most intriguing questions. More than 600 particle physicists from nearly 100 universities and laboratories came together on the University of Minnesota’s Minneapolis campus to enumerate the field’s most pressing scientific questions and contemplate the experiments needed […]
Deputy Linear Collider Director Hitoshi Murayama says that for the ILC, momentum is key.
The Snowmass meeting has just finished with a great deal of enthusiasm. I’m writing this article as I wait for my flight at Minneapolis-St. Paul airport under the lingering excitement from the meeting of more than 700 physicists. We discussed about the future of high-energy physics in the US and laid out scientific opportunities. There […]
Let me take this opportunity to acknowledge the enormous achievement of the very small GDE team, led by Barry Barish. They have produced the Technical Design Report, which has been favourably reviewed by an independent expert committee. The TDR also contains a detailed cost estimate which has also been independently reviewed and has proved to […]
