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 […]
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 […]
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 […]
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. […]
New Humboldt professor Brian Foster takes office at DESY
In June, Brian Foster will take up his work at DESY and University of Hamburg as a joint professor for experimental physics, with a focus on accelerators for very high energies. He is one of eight professors who won a Humboldt professorship this year, the most outstanding research prize in Germany, endowed with 5 million […]
Brian Foster awarded Alexander von Humboldt Professorship On 12 May in Berlin, the Alexander von Humboldt Foundation presented one of eight Humboldt Professorships, the highest valued international awards for research in Germany, to Brian Foster. Beginning 1 June, Foster, the GDE Regional Director of Europe, will begin work at the research centre DESY and at […]
Automated cavity inspection makes progress at DESY
If you have bought a digital camera recently, you probably enjoyed the new ‘smile detection’ feature that many new cameras are equipped with. It works like this: you set the camera to smile detection mode and point it at somebody. The camera recognises faces and as soon as the face smiles, snap – it takes […]
