Accelerator theory and operating experience are all well and good. But if you’re planning and researching the next-generation particle accelerator, you sometimes need to crank things to their limits in order to get a step further. The 9-mA team has descended again on DESY’s FLASH accelerator in March to share control room space with the DESY […]
More knobs, more knowledge
Long-bunch-train ILC studies are back at FLASH
ILC technology in the Guinness Book of World Records!
Good gradients in seconds flat
Fermilab scientists turn their attention to individual cavities to improve beam stability
A constant acceleration gradient along many thousands of particle bunches provides for a particle beam’s sure-footed climb to higher energies, readying the beam for collision by providing the same acceleration for each bunch. But constant gradients don’t come naturally for accelerating cavities, the elements that pave the particles’ ascending path. A cavity has to be […]
Achieving cavity resonance
DESY scientists fine-tune cavity frequencies
Accelerator scientists have been busy creating and combining sine waves and nonlinear curves to form a straight, horizontal line – the flat top of a signal pulse of electric field-accelerating electrons. The flat, even profile signifies the untroubled transfer of power from source to electrons, one that occurs when a cavity is in tune with […]
All aboard the long bunch train
Collaborators for the ILC and for DESY’s FLASH facility learn from long bunch train studies at a recent workshop
For all the complicated engineering and hulking structures involved in operating particle accelerators, it’s the tiny, invisible particle beam at the centre of everything that is the machine’s reason for being. A probe for burrowing into subatomic places or a light to shine on molecular forms, the beam is science’s exploratory tool for the universe’s […]
A new beginning – and no strings attached
This week’s issue features a Director's Corner from Brian Foster, Global Design Effort European Regional Director.
When Albrecht Wagner, former chair of the DESY directorate, first suggested to me that I might consider applying for an Alexander von Humboldt Professorship in association with Hamburg University and DESY, I didn’t take the idea seriously. I had no intention of leaving Oxford, which is a fantastic place both to live and to work. […]

From DESY: Record wavelength at FLASH
Cryomodule surpasses ILC gradient test
European-XFEL cryomodule using SCRF technology sets new record
A cryomodule prototype for the European XFEL has set the world gradient record for cryomodules built with superconducting radiofrequency technology, reaching an average accelerating gradient of more than 32 megavolts per metre (MV/m) in recent tests. This is an important step towards major goals set for the ILC’s Technical Design Phase (TDP), which include demonstrating […]
