From SLAC today: People: Andrei Seryi

15 October 2009 Since beginning his career in 1986, SLAC senior scientist and project manager for FACET Andrei Seryi has worked at five labs in three countries, with the last 10 years at SLAC. In this decade, Seryi has led international collaborations to design and build linear accelerator experimental facilities, all while continuing his accelerator research and design projects at SLAC.

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.

From SLAC Today: New Modulator Prototype Put to the Test

25 June 2009 Yesterday, a team of physicists and engineers from SLAC National Accelerator Laboratory completed initial testing on a new power source, the Marx modulator, connected to its target device, and launched a yearlong test. This test will be the final step in proving the reliability of a device poised to transform the way particle accelerators are powered. Category: Around the World | Tagged: ,

From SLAC Today: Simulating a More Efficient Linear Collider

11 June 2009 The team, from SLAC's Advanced Computations Department, or ACD, is researching how to minimize the effects of charge "wakes" in the ILC, which will smash electrons and positrons into each other. As bunches of these particles race down accelerator tracks, electromagnetic wakes rise behind them. These wakefields can make the going rough for bunches to come, causing some particles to stray off course. As a result, beam quality can suffer and heat can build up inside accelerator cavities, potentially degrading their performance. Category: Around the World | Tagged: ,

From SLAC Today: A Flight Simulator for the World’s Smallest Beam

2 April 2009 Commissioning has begun at the Japan-based Accelerator Test Facility 2, a major technology test bed for future accelerators, including the proposed International Linear Collider, or ILC. During the two-year commissioning process, SLAC National Accelerator Laboratory physicists are shuttling back and forth to KEK, the high-energy accelerator lab in Tsukuba, to join an international team of scientists working around the clock to get the accelerator's final focus system up and running. When fully commissioned, this system will squeeze the facility's electron beam down to a slender ribbon just 35 nanometers thick—the narrowest beam of particles ever achieved.

Life after the LOI

19 March 2009 A Silicon Detector (SiD) workshop was held at SLAC from 2 to 4 March, with the express purpose of reviewing the status of the SiD Letter of Intent, organising the final steps in its completion, and beginning to think of life after the LOI. Category: Feature | Tagged: , ,

From SLAC Today: Groovy Beam Pipe Update

29 January 2009 Something unwanted lurks within accelerator beam pipes around the world: stray electrons. This haze of electrons interacts with positron and proton beams, often causing distortion. Previous tests showed that an insert designed by SLAC researchers works well to capture stray electrons in an environment with no magnetic field. Now, recent tests carried out at the Japanese accelerator facility KEK confirm that a new insert can reduce this electron cloud effect in a magnetic field. Category: Feature | Tagged: ,

From SLAC Today: Marx Modulator Begins Testing in End Station B

4 December 2008 This week SLAC National Accelerator Laboratory moves one step closer to producing an innovative new piece of the International Linear Collider. The first-generation model of a new design for equipment that helps power the accelerator is moving from the SLAC Power Conversion Department to End Station B, where it will undergo long-term testing.

Discussing the future – SLAC ICFA Seminar

| 4 December 2008 Visionary thinkers converged at SLAC for an ICFA Seminar (International Committee for Future Accelerators) on possible future projects for particle physics during the last week in October. Category: Director's Corner | Tagged: ,

From SLAC Today: ICFA Sharpens Focus on the Energy Frontier

6 November 2008 "Particle physics is at a crossroads," said Chairperson Albrecht Wagner of the International Committee for Future Accelerators, in the opening moments of the ninth ICFA Seminar last Tuesday in Kavli Auditorium. "The Standard Model stands triumphant," Wagner said, "yet incomplete." Category: Feature | Tagged: ,
