It's meeting season in North Japan: a series of workshops held in Ichinoseki as well as in Tokyo brings together linear-collider scientists from all sorts of backgrounds: polarisation, particle sources, detector design, physics studies, and, coming up, machine-detector interface and civil engineering.

A team at DESY has created a complete virtual-reality three-dimensional ILC. They have combined information from various computer-aided design systems and about all areas of the ILC together in one model that you can now walk through. This model can highlight problems before they become costly and is a great motivator for the owners of the individual systems.

A group of Chinese scientists, headed by Xuejun Jia from the Institute of Physics of the Chinese Academy of Sciences, recently finished the design of the remote handling of the ILC positron target. The target forms part of the positron source and is the place where positrons are produced and then accelerated before they collide with their antiparticles, the electrons.

The last of four proposed major changes to the ILC baseline is to move the positron source to the end of the linac. That proposal has been adopted after evaluating the advantages and the possible options to retain low-energy performance.

The ILC’s flux-concentrating magnet operates much like someone in a high-intensity interval workout: it fires for only a small fraction of the time, but when it does, it takes a beating. Scientists at Lawrence Livermore National Laboratory have finished the intense work of designing the flux concentrator, modelling its operation and potential hurdles.

Scientists from the Cockcroft Institute, Daresbury Laboratory and Lawrence Livermore National Laboratory work on a rotating positron target for the ILC that can hold its own while producing about 1014 positrons per second for collisions with electrons.

The SLAC BAW was the second and last such workshop of the so-called Top Level Change Control (TLCC) process, which has been going on for the last twelve months. The SLAC BAW focused on the two remaining TLCC themes: a reduced beam-power parameter set and the location and layout of the positron source.

The team developing the ILC's positron source have every reason to be positive. Recent tests have shown both that the four-meter helical undulator prototype – a device that will produce an intense beam of polarised gamma rays – works in its cryomodule, and that the target that will produce the positrons themselves can reach its design rotation speed of 2000 revolutions per minute.
