GDE Executive Committee visits Washington DC

by Barry Barish

During a face-to-face working meeting of the Global Design Effort Executive Committee, held in Washington DC last month, invited guests discussed with us how science is supported in the US system, including new project approval, the yearly budget process and the formulation of science policy.

The incredible shrinking pixel sensor

by Leah Hesla

We don’t usually notice all three dimensions of a semiconductor chip. We note the intricate, maze-like circuitry imprinted onto one side or its reflective sensor surface. Rarely is attention paid to its depth, mostly because chips have so little of it. In the last five to ten years, the particle detector community has been working with the semiconductor industry to develop sensors’ minuscule depths to create technology with integrated functionalities that could be used in fields outside particle physics.

Japanese civil engineers dig deep in Europe

A contribution from the Global Design Effort's civil engineering team

by Wilhelm Bialowons (DESY), John Osborne (CERN), and Masanobu Miyahara (KEK)

Ten members from the Japanese Society for Civil Engineering’s committee for civil works for future ILC facilities came to Europe in February to look at current civil engineering projects like CERN’s LINAC4 and the European XFEL in Hamburg and to discuss administrative challenges. By the end of March next year, the committee will publish draft guidelines on civil solutions for a potential ILC in Japan.

    Ever since scientists in Italy announced in September that they appear to be seeing particles called neutrinos travelling faster than light people have been trying to poke holes in their findings. Perhaps none more so than the boffins from the OPERA collaboration responsible for the furore.

    During the meeting, a decision was also taken to create a European committee to review the R&D effort for future projects. High-energy physics relies heavily on detector R&D developments: every significant improvement in detection techniques opens a new area for fundamental-physics research. Considerable amounts of labour and financial resources are committed to this field across Europe and around the world.
