Tokyo, 15 December. The draft of the Technical Design Report (TDR) for the planned International Linear Collider ILC was handed over to Jonathan Bagger, the chair of the International Linear Collider Steering Committee (ILCSC), at an official ceremony in Tokyo, Japan, on 15 December. This draft is the product of many years of research and development and a series of in-depth technical reviews for the ILC, the potential next-generation particle collider to complement and advance beyond the physics of the Large Hadron Collider at CERN. The handing over of the TDR draft marks the ILC's major step towards the completion of its final design.
After the official handover ceremony of the TDR draft in Tokyo last Saturday, ILC experts, policy makers and members of industry discussed the potential of building the ILC in Japan. One conclusion was that physicists from all over the world would be welcome in Japan, even though they may be considered strange by some.
One of the key objectives of the ILC R&D programme during the Technical Design Phase has been to characterise electron cloud effects in an ILC-like low-emittance positron damping ring and to test proposed mitigation techniques. The centerpiece of our efforts has been the CesrTA programme that involved reconfiguring it as an ILC-like low emittance ring and instrumenting it to carry out these studies. CesrTA has been a highly successful experimental programme, leading to reliable mitigation strategies for the ILC positron damping rings.
The German lab DESY is saying good-bye to one of its accelerator workhorses, the DORIS ring. On 2 January 2013 the final beam will go round its tunnel. It has already stopped being a light source: the last positron beam reached the HASYLAB experimental huts on 22 October. Between then and now, DORIS reverted to its original raison d’etre: an accelerator for particle physics.
Will Japan build the next generation of particle collider? The International Linear Collider could help particle physicists study the Higgs boson, the particle that helps endow all others with mass. The ILC exists only on paper and will cost billions to build. (with nature video)
LDP campaigned heavily on reviving Japan’s stagnant economy through spending on public works, including at least one big science project. The party platform specifically mentions support for the proposed International Linear Collider, a $10 billion physics project that Japan’s high-energy physicists are anxious to host.
A technical design report for an envisioned large next-generation particle accelerator has been completed and was submitted to a committee overseeing the project at an official ceremony in Tokyo on Saturday.
On 15 December, scientists will celebrate the completion of the technical design report for their dream machine, the International Linear Collider. But figuring out where to build it and who will pay for it will be an even bigger challenge.
