The capability for producing niobium sheets

| 26 January 2012 Japanese company Tokyo Denkai is boosting high-purity niobium production and processing with some new equipment and a better-outfitted shop. Should the ILC be built, the company will be able to handle the large order of niobium needed for accelerator cavities. Category: Around the World | Tagged: , , , , ,

The multiplying effects of an accelerator economy

| 3 November 2011 A company in Lansing, US is developing accelerator cavities for the ILC. In the course of improving these high-tech devices, it has enhanced its expertise in developing them for other areas of science and, as an added benefit, sustaining the technology R&D.

All aboard the long bunch train

| 30 June 2011 Learning to stabilise a particle beam of longer pulses such as those needed for the ILC requires diligence, patience and practice. ILC and FLASH scientists share the fruits of all three at the recent workshop on long bunch trains. Category: Feature | Tagged: , , , ,

I have a dream…

| 31 March 2011 Is it possible to build a strong, long-term and globally coordinated accelerator R&D programme? Most probably, and Jean-Pierre Delahaye wishes to. In this week’s director’s corner, he explains how, referring to a review of new accelerator projects he presented at ICHEP2010 conference in Paris last year. Category: Director's Corner | Tagged: ,

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: , , , , , ,

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.

ILC technology gets awarded

| 16 April 2009 On 23 March, the 2008 Nishikawa Award Ceremony was held in Tokyo, and awards were given to three ILC scientists: Yoshihisa Iwashita (Kyoto University), Hitoshi Hayano (KEK) and Yujiro Tajima (Toshiba Co., Ltd). Category: Feature | Tagged: , , ,

Time to recover

| 31 July 2008 In a linear accelerator, energy conservation is not really on the achievement list. To get up to the required luminosity, accelerator experts have one chance to push the particle beams to their limits, putting much energy into the bunches, correcting, scraping and tweaking them along the way only to smash them into each other and direct the straggly remains into a dump. Not so an Energy Recovery Linac, currently at the design and first prototype stage at Cornell University. The electron beams also get dumped after one run, but before that happens, they are tricked into handing over their energy back to the superconducting machine that accelerated them.

Second sound sounds promising

| 26 June 2008 “Our superconducting technology group here at Cornell is doing some very fundamental R&D,” says Hasan Padamsee, physics professor at Cornell university and expert in superconducting rf technology. “Note that the stress is on the fun in fundamentals.” Students are even allowed to drill holes into cavity prototypes in order to find out what makes certain areas in the material behave differently from others. A new mapping technique, invented by Cornell's Don Hartill, Zach Conway and Eric Smith, could make it possible to locate quenches during cavity tests with just eight (instead of up to 180) thermometers.

From SLAC Today: Clearing Clouds

9 August 2007 Clouds might be welcome during a drought, but you definitely don't want them in your beam pipes. Researchers around the world are working out how to keep a section of the proposed International Linear Collider—the positron damping ring—clear of electron clouds. Category: Feature | Tagged: , , ,
