The breadth of activities carried out by professional societies is truly impressive, from publishing and organising conferences to affecting physics education, science policy and public outreach. Most of us belong to a professional society that serves as a professional home in our county. I have belonged to the American Physical Society since I was a […]
HEPAP: advising DOE on the particle physics programme
As US Regional Director, Mike Harrison usually covers US High Energy Physics Advisory Panel (HEPAP) meetings as a way to stay abreast of developments in and the direction of the US high-energy physics programme. This time, instead of Mike, I attended the recent HEPAP meeting in Washington DC on 12 and 13 March. At this […]
KILC12 in Daegu: a preview
The Linear Collider Physics/Detector Group of ACFA (Asian Committee for Future Accelerators) and the Global Design Effort (GDE) of the ILC are sponsoring a joint ACFA physics and detector workshop and GDE meeting on the International Linear Collider. The meeting, called KILC12, will be held in Daegu, Korea from Monday April 23 through Thursday April […]
Advances in SCRF cavity performance in the Technical Design Phase
This week's issue features a Director's Corner from Akira Yamamoto, Project Manager for the Global Design Effort
The current ILC superconducting radiofrequency (SCRF) cavity design is based on the so-called TESLA type (the elliptical shape as shown at left), a 1.3-gigahertz (GHz) nine-cell cavity. The design gradient has been set at 35 megavolts per metre (MV/m) and an average quality factor (Q0) of greater than 8×109 to realise the stable, long-term operation […]
GDE Executive Committee meets face to face
The Global Design Effort (GDE) Executive Committee met face to face in Washington, DC, from 8-9 February at the offices of the American Physical Society. The GDE Executive Committee is the senior responsible body for the GDE and advises me on the broad range of science and policy issues involved in directing our efforts. Being […]
ILC Project Implementation Planning: the prequel / the draft
In order to make our ILC design as realistic as possible, we have considered many of the issues that will need good solutions when the ILC is built. As a result, we have developed and submitted a draft document to the International Linear Collider Steering Committee (ILCSC) as a starting point towards an actual ILC […]
The International Linear Collider Steering Committee plans for the future
The International Linear Collider Steering Committee (ILCSC), a subcommittee of the International Committee for Future Accelerators (ICFA), provides oversight to the Global Design Effort. As we approach our final milestone, the publication of the ILC Technical Design Report, the ILCSC is in the process of creating a new organisational structure and mandate for future work […]
GDE Executive Committee visits Washington DC
The Global Design Effort (GDE) Executive Committee met for a face-to-face meeting in the Washington DC offices of the American Physical Society from 8-9 February. At that meeting, we invited some guests to inform us about how science policy and funding work in the US government. Our mandate for the GDE is soon approaching its […]
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 […]
Moving towards one linear collider project
The International Linear Collider (ILC) is based on superconducting radiofrequency technology, while the Compact Linear Collider (CLIC) uses a two-beam acceleration concept. The ILC technique is more mature and the design more advanced: we are now putting together a detailed Technical Design Report that could serve as the basis of construction project. The CERN-based CLIC […]
