The International Linear Collider had more than a dozen circuit pixel-detector technologies to choose from for their vertex detectors. Now, they can choose from many more design options thanks to a ground-breaking partnership among national laboratories, universities and industry.

Just a 15-minute walk from Matsumoto Castle in Nagano prefecture, which is considered a national treasure of Japan, you’ll find Shinshu University, where the International Conference on Photon Detectors, or PD09, was held from 24 to 26 June. The conference was attended by 55 photon-sensor experts in the field of high-energy physics, nuclear physics, cosmic-ray physics and medical science, along with three companies–Hamamatsu, SEIKO EG&G and General Electric–to discuss the recent development of photon-sensors and various applications. In 2007, both the ILC and the T2K neutrino experiment project groups initiated this bi-yearly conference in Kobe to collaborate on the use of the multi-pixel photon counter (MPPC) and other newly developed photon-sensors.

Scientists just finished successfully testing the first particle flow algorithm hadronic calorimeter for the International Linear Collider, with unprecedented granularity and novel readout technology. This sub-detector, the analog hadronic calorimeter, was built by the CALICE (Calorimeter for the Linear Collider Experiment) collaboration and is one of several options for the hadronic calorimeter of a future ILC detector.

Yesterday, a team of physicists and engineers from SLAC National Accelerator Laboratory completed initial testing on a new power source, the Marx modulator, connected to its target device, and launched a yearlong test. This test will be the final step in proving the reliability of a device poised to transform the way particle accelerators are powered.

Nearly every one of the myriad complex components of the International Linear Collider pushes the limits of today's technology, and for the ILC to succeed, each one of them has to work as designed. Researchers at the University of California, Davis (US) are concentrating on the interconnects – the connections between arrays of electronic circuit elements – in the ILC's proposed Silicon Detector Design Study (SiD) concept detector. The group is applying new technologies and advanced materials to improve the performance, efficiency, ease of assembly and robustness of these critical detector components.

The team, from SLAC's Advanced Computations Department, or ACD, is researching how to minimize the effects of charge "wakes" in the ILC, which will smash electrons and positrons into each other. As bunches of these particles race down accelerator tracks, electromagnetic wakes rise behind them. These wakefields can make the going rough for bunches to come, causing some particles to stray off course. As a result, beam quality can suffer and heat can build up inside accelerator cavities, potentially degrading their performance.

TILC09 in Tsukuba, Japan, took place on Japanese Invention Day observed annually on 18 April, and the week in itself was designated as Science and Technology Week. Naturally, in Tsukuba, the population of research institutions is unparalleled in the country, and it becomes most festive during that week once a year. There were various events held throughout the nation during the week of 13 April, one of which was the TILC09's public lecture, "The universe's greatest magic!? – Antimatter annihilation" featuring a close-up magician, Tomohiro Maeda, Hitoshi Murayama of the Institute for the Physics and Mathematics of the Universe (IPMU) and Takeo Higuchi of KEK.

In early September 2009, Beijing will serve as host city to roughly 70 outstanding physics students from the Americas, Asia and Europe for a ten-day intensive course entitled the Fourth International Accelerator School for Linear Colliders. The Institute of High-Energy Physics (IHEP) will be the host institution. Led by scientific researchers and academic faculty, the rigorous curriculum will address such topics as linear colliders, the muon collider, radiofrequency technology and damping rings. It will be yet another step forward in the tenure of the school which took place at such locations as Hayama, Japan, Erice, Sicily, Italy, and Oakbrook, Illinois, U.S.A., in previous years.

Most particle physicists think that the International Linear Collider (ILC) could revolutionise our understanding of the universe, and will challenge inquisitive minds of particle physics. This is a field where University of Notre Dame in Notre Dame, Indiana, US, has been actively participating, particularly in muon detector research and in organising outreach activities between students, high school teachers and physicists.
