SLAC All Access: klystrons on YouTube

18 October 2012 SLAC's YouTube channel has more on klystrons, and of course the legendary klystron gallery. In a video about SLAC's Vacuum Microwave Device Department (VMDD), introduces itself as those people who build the devices that make SLAC's particle accelerators go: klystrons. These devices generate intense waves of microwave energy that rocket subatomic particles up to nearly the speed of light. Department head Andy Haase takes us behind the scenes where klystrons are born. These devices are developed, designed and fabricated by teams of physicists, engineers and technicians in coordination across several departments within SLAC's Accelerator Directorate.

| 18 October 2012 Superconducting cavities accelerate particles using radiofrequency (RF) power. But where does the power to accelerate a beam by millions of electronvolts come from? The ILC’s power source can provide only about 100 watts, but to push that power up to the required level you need a device called a klystron. The klystron is a power amplifier. It can expand a few tens of watts into millions, or megawatts. Each ILC klystron will supply amplified power to 39 superconducting cavities for the baseline design. Category: LCpedia | Tagged: , ,

More knobs, more knowledge

| 29 March 2012 In their unflagging quest to achieve higher gradients for the ILC, scientists in the 9-mA study programme at DESY’s FLASH facility develop a better knack for automating accelerator voltages, helping keep cavity gradients high and the whole system stable.

Many small klystrons for operability and flexibility

| 10 February 2011 Scientists at KEK in Japan are currently developing a 'distributed radiofrequency system' for delivering radiofrequency power to the ILC accelerating cavities. An alternative solution to the 'klystron cluster scheme', this powering method accommodates the ILC’s new one-tunnel design. Category: Around the World | Tagged: , , , , , ,

Clustering klystrons to pool power

| 3 February 2011 Though it doesn’t sound like a way to tidy up, the alliteratively named klystron cluster could be the mechanism that helps streamline the large-scale design of the ILC. Scientists at the Stanford Linear Accelerator Center (SLAC) in the US are currently developing the klystron cluster scheme, a new kind power-delivery system for radio frequency cavities that distributes power from a common conduit.

From SLAC today: Bringing Power to the International Linear Collider

1 October 2009 At SLAC, accelerator physicists Chris Adolphsen and Chris Nantista are working on one point that has proven to be particularly prickly: figuring out how to provide the accelerator with the power needed to drive the machine's high-energy particle collisions.

A horizontal challenge

| 17 January 2008 The world’s first horizontal multi-beam klystron has started its site acceptance test at DESY. Built by the Japanese company Toshiba, it is the first of three prototypes from different companies to arrive for the test that will determine whether the new klystron design works. The 10-megawatt horizontal klystron was developed for the European X-ray Free Electron Laser (XFEL) and is also part of the reference design for the ILC. Category: Around the World | Tagged: , , , ,

From SLAC Today: ILC’s Marx Modulator

1 February 2007 The current design for the International Linear Collider (ILC) requires 576, 10-megawatt klystron tubes to supply microwave power along its 40 km linear accelerator. Each ILC klystron tube needs 120,000 volt, 140-ampere pulses, fired at a rate of five pulses per second. Each pulse delivers a total energy of more than 23 kilojoules—the kinetic energy of a 20 millimeter cannon shell. Category: Feature | Tagged: , ,
