This year is the 100th anniversary of the discovery of superconductivity, a state in some materials to conduct electricity without energy loss at very low temperatures. Heike Kamerlingh Onnes demonstrated the phenomenon of superconductivity in 1911 at the University of Leiden in the Netherlands when he observed the resistivity of mercury go to zero as […]
The new baseline and the next steps
Today's issue features a Director's Corner by Ewan Paterson, member of the Global Design Effort Executive Committee.
In an opening plenary session at ALCPG11 in Eugene, Oregon, I summarised the history and status of the process towards a new baseline for the design of the ILC. I present only an overview here. The year-long Top Level Change Control (TLCC) process was completed just in time for the Eugene meeting and is shown […]
Positron source relocated to the end of the linac
Three major changes to the Reference Design Report (RDR) baseline have previously been adopted. Today, I announce the approval of the fourth and final top-level baseline change that has been proposed by the Global Design Effort project managers. The undulator-based positron source will be relocated from the 150 GeV energy point to the exit of […]
Low-power option adopted for ILC technical design baseline
Cost containment has been a consistent theme underlying proposals to define a new baseline for the technical design effort and report. Some changes are the result of further studies after we developed a reference design for the ILC, while others have required invoking some new ideas. One of the four major changes that were proposed […]
ILCSC reviews GDE progress and plans
The International Linear Collider Steering Committee (ILCSC), a subcommittee of the International Committee for Future Accelerators (ICFA) that provides scientific oversight for the Global Design Effort (GDE), met in Beijing on 17 February 2011. Of special interest at this meeting were discussions of the future of the efforts towards the ILC, after the ILC Technical […]
I have a dream…
This week's issue features a Director's Corner from Jean-Pierre Delahaye, member of the GDE Executive Committee and CLIC study leader.
As a newcomer to the Global Design Effort Executive Committee nearly two years ago, I was invited to write for ILC NewsLine’s Director’s corner, which I dedicated to one of my favorite subject: “The Beauty of Collaborations”. I would like to take this new opportunity to address a complementary subject with a plea for a […]
Introducing the new ILC NewsLine
Welcome to the new ILC NewsLine! This is the first issue of a new style, with a modern look and feel, new logo, more cohesive page design and navigation, wider format, larger images and added features and functionalities. Since 2005, ILC NewsLine has been our main tool for communicating the continuous progress of our ILC […]
To our Japanese colleagues
FALC discusses future programmes in particle physics
The Funding Agencies for Large Colliders (FALC), an informal committee of particle physics funding agency representatives, held their eighteenth meeting at SLAC on 22 January 2010. I previously reported on an interesting exchange meeting between the Global Design Effort Executive Committee and FALC that took advantage of the fact that their meeting immediately followed our […]
Progress in the nanometre world
Today's issue features a Director's Corner from Toshiaki Tauchi, a member of the EC.
This is the second time I contribute an article for this column. Last April, I reported that we have entered the nanometre world by tuning the beam size just below one micrometre at ATF2, a test facility for the final focus system at KEK, Japan. Since then, there have been two experimental runs for one […]
