PAC meeting in Taiwan: a discussion of long-term issues
|
The ILC Program Advisory Committee met at Academia Sinica in Taiwan in May. In addition to their specific recommendations, they again urged development of a strategy for the post-2012 period, following completion of the accelerator Technical Design Report.
FeatureFrom symmetry magazine: Adventures of a light-source bum
I got involved in particle accelerators as a graduate student because I wanted to work in an area that had the potential to have a positive impact on people’s lives in 10 to 20 years. Near the end of my PhD studies, I attended a talk by Herman Winick, who introduced the audience to synchrotron radiation sources and the research going on at the SPEAR ring at what is now the Stanford Synchrotron Radiation Lightsource, SSRL.

Around the WorldAchieving cavity resonanceDESY scientists fine-tune cavity frequencies
Keeping accelerating cavities tuned to the right frequency requires continual, gentle hammering by a little device called a piezoelectric tuner. DESY scientists have mastered the art and science of applying the piezo to cavities, bringing them to within several ten-thousandths a percent of the desired frequency.

Cavities in stereoUsers can take a virtual tour through the European XFEL tunnel, currently under construction, walking through the newly planned facilities to get an idea of its space and future working conditions. The nine-cell structures of pure niobium are designed to speed up the electrons at DESY’s FLASH, the European XFEL, and the ILC. The picture was taken in DESY’s IPP stereo projection room, where it is possible to project and view three-dimensional models on a 1:1 scale. |
