Creating polarised positron beams
Today's issue features a story from Tohru Takahashi, a particle physicist and associate professor at Hiroshima University. He is the co-author of "Big-Bang wo tsukuridase" (Making the Big-Bang), a book about the ILC.
Participants of the PosiPol Workshop held in Hiroshima, Japan. |
The PosiPol2008 workshop was held from 16 to 18 June in Hiroshima, Japan. An unfamiliar word, "PosiPol" stands for "polarised positrons", meaning that the "spins" of positrons are aligned when they meet electrons at the centre of a linear collider. The electron beam is designed to be polarised at the ILC, but according to the baseline configuration positrons are unpolarised (or left naturally polarised) because making polarised positron is a difficult task to do.

From interactions.org: Five million Euros to prepare Europe for the International Linear Collider
ILC-HiGrade will produce a mini series of cavities. |
The partners of the 'ILC-HiGrade' proposal for the European Commission's Seventh Framework Programme have just started a contract for five million Euros funding over the next four years with the European Commission. 'ILC-HiGrade' stands for 'International Linear Collider and High Gradient Superconducting RF-Cavities.' One of the main objectives of the proposal is a small serial production of accelerating cavities, superconducting components made of pure niobium for the planned International Linear Collider (ILC), that reach the high technical standards needed for the planned particle physics project. Other objectives of the ILC-HiGrade proposal are the development of a possible organisation and governance for the ILC and measures to prepare for the actual construction of the machine, including a detailed study on possible sites in Europe.

As LHC Draws Nigh, Nobelists Outline Dreams--And Nightmares
...Gross said that such a result, going against the standard model, would itself be "enormously exciting." What worried him was finding the Higgs and nothing else, because then it would be impossible to persuade world governments to fund future machines such as the proposed International Linear Collider,

The ILC-ECFA Workshop in Warsaw
Stefan Pokorski describes various scenarios for physics at a linear collider. |
From 9 to 12 June, the Faculty of Physics at the University of Warsaw, Poland, together with the Institute of Nuclear Studies hosted a workshop under the mandate of the European Committee for Future Accelerators (ECFA) to discuss the physics and detectors for a linear collider. This well attended workshop covered a broad range of topics from the physics of a linear collider to R&D for detectors. The attendants discussed the physics in advance of and preparing for the first results from the Large Hadron Collider (LHC) at CERN that will set the future course for the energy frontier.
