Good gradients in seconds flat

| 4 August 2011 A stable particle beam needs a trouble-free path on its way to high energies, and that means providing it with a smooth gradient to ascend. A team of scientists at Fermilab has arrived at a way to control accelerating cavities so they can give particle beams exactly that – a tilt-free path to collision.

Achieving cavity resonance

| 7 July 2011 Keeping accelerating cavities tuned to the right frequency requires continual, gentle hammering by a little device called a piezoelectric tuner. DESY scientists have mastered the art and science of applying the piezo to cavities, bringing them to within several ten-thousandths a percent of the desired frequency.

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: , , , ,
