A new generation of undulator magnets

| 13 January 2011 Lately, scientific communities are in need of higher-energy light particles. To do this, scientists are extending the existing technology of undulator magnets, or undulators. The device uses magnets to wiggle a particle beam into giving up light, which can then be used for a whole host of scientific applications. Category: Feature | Tagged: , , , , , ,

Wei Gai leads positron source efforts for ILC

| 6 January 2011 Scientists at the ILC who deal in matters positively charged have a new go-to guy: Wei Gai. This month, Gai assumes the role of the ILC's Positron Technical Area Group Leader (Positron TAGL). He takes over the position from Jim Clarke at the Science & Technology Facilities Council/Daresbury Laboratory in the UK, who has given up the role because of the UK's changing programme priorities.

Spiralling under control

| 11 June 2009 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.
