Mastery of difficult technologies is in the DNA of high-energy physics and the accelerators that enable the science. For many decades ever increasing beam energies and intensities have given rise to not just spectacular science results but also to a well documented stream of technical innovations which have resulted in spin-offs in many non-related fields.

The two detector concepts for the ILC
Since the inception of the ILC design effort, we have been developing the concepts for detectors to do the science as an integral part of our work. The interactions between the accelerator and the detectors are complex and demanding. For that reason, we have a group of accelerator and detector experts working together on machine-detector […]
How long is the ILC linear accelerator?
This week's issue features a Director's Corner by Ewan Paterson, member of the Global Design Effort Executive Committee
How long is the ILC linear accelerator? This simple question does not have a simple answer. In the first place, the electron linear accelerator, or linac, is longer than the positron linac because it’s the electron beam’s responsibility to produce the positrons, so part of the electron linac’s length is dedicated to that task. The […]
Our goals for 2012
Happy New Year! Today is a good time to take stock of what we achieved last year and reflect on our goals for the coming year. The primary goal for 2011 was to establish a new ILC baseline that would be better optimised for cost, performance and risk, as well as to carry out the […]
Decisions, decisions, decisions
In ILC NewsLine last week, Nick Walker wrote a guest Director’s Corner where he outlined the steps to the Technical Design Report (TDR) and Barbara Warmbein wrote a feature article summarising some highlights of the Baseline Technical Review (BTR) meeting at DESY. Today, I write a third article on the same basic subject of how […]
Technical baseline reviews: damping rings
Over the past two years, the GDE has concentrated its efforts on advancing critical ILC R&D in order to reduce risks and to demonstrate performance. In parallel, we have established a new, more coherent and more cost-effective baseline to be used for the next phase of developing the technical design that will be incorporated in […]
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 […]
Interim report from the ILC-CLIC general issues group
On 11 January 2010 the ILC Steering Committee and the Compact Linear Collider study (CLIC) Collaboration Board created a working group to exploit synergies and discuss general issues involving the linear collider. That group has met regularly throughout the last year and submitted an interim report to their respective oversight groups this month. So far, […]
