And Still They Will Collide

| 20 August 2015 Is the beam delivery system delivering? Ten years ago, at the Global Design Effort’s formative meeting in Snowmass, Colorado, ILC communicator Perrine Royole-Degieux interviewed Phil Burrows, then professor at Queen Mary University of London, about the beam delivery system. How has the home straight where the particle bunches get squeezed, focused and brought to collision, evolved in a decade? Category: Feature | Tagged: , , , ,

Spin doctors

| 8 May 2008 Theorists and experimentalists aren't always of the same opinion. There is one thing on which opinions aren't polarised though, and that is polarisation. Polarisation is a special characteristic of a particle bunch – a sort of measure of the particles’ combined spin – that, when studied in the right sort of detector at the ILC, is supposed to give clues and answers on phenomena like the Higgs, supersymmetry or searches for new physics and extra dimensions. To study the collisions, and also to understand polarisation better, a few groups of a total of about 30 people around the world are designing and building polarimeters that measure the degree of polsarisation of the particles before and after collisions. They have just had their first 'collaboration' meeting at DESY in Zeuthen, near Berlin, Germany. Category: Around the World | Tagged: , , , , , ,

The Evolving ILC Design: Centralising the Injectors

| 21 December 2006 I report today on another design change that has resulted from our ongoing cost to performance optimisation studies, which we are carrying out before finalising the ILC reference design. Category: Director's Corner | Tagged: , ,

The Evolving ILC Design: Changing the Crossing Angles

| 21 September 2006 Optimising cost to performance for the ILC design is a challenging task. Our working groups have identified a number of possible design changes, motivated by large potential cost savings. Category: Director's Corner | Tagged: , ,
