Making Waves for Positrons
Members of the HeLiCal collaboration with the undulator ready for testing. |
The ILC's positrons might be wondering where their second damping ring has gone and whether to get damped in the middle or at the end of the machine. Where they come from, however, is pretty clear, and teams in the UK and the US are making sure that their moment of creating is both well controlled and well understood. A 4th –generation undulator prototype has just been tested at Rutherford Appleton lab in the UK, and tests are looking very good.

| My Favourite Year
Carleton University student recalls his year as a member of an ILC TPC Micromegas French group.
At only 23 years old, Dan Burke, an undergraduate student from Carleton University, Canada, had already experienced the scientific excitement and the various activities of research in particle physics. Last year he stayed in a French Laboratory at Dapnia, Saclay and participated in various measurements, test beams and physics analyses and contributed to two scientific publications.

Burke spent a year as a member of the TPC Saclay Team, directed by Paul Colas. This group's major activity is R&D for the Micromegas (MICRO-MEsh GASeous detector) Time Projection Chamber (TPC), within the LC-TPC (Time Projection Chamber) international collaboration (see NewsLine 22 June 2006). While crossing a gas-filled cylinder TPC detector, charged particles ionise the gas. In Micromegas chambers, the produced electrons drift and are amplified between fine metallic micromesh structures and anode pads readout.

How the US Sees the LHC
"Particle physicists in the US are excited about their involvement in the Large Hadron Collider, but Nigel Lockyer says they must ensure their future after 2010 once all the major US high-energy-physics accelerator programmes have ended..."

Road to the ILC Reference Design
The GDE Schedule to complete the Draft Reference Design Report and Preliminary Costing. |
The next big goal for the Global Design Effort is to produce an ILC Reference Design Report (RDR) that will include Preliminary Costing. We are systematically working toward this goal, and have now progressed far enough to set a realistic schedule. In recent columns, I highlighted some of the evolution of the baseline resulting from either technical advances from our R&D programme or from cost to performance optimisation. Several more studies are underway, and we expect to evaluate these in the coming weeks, especially at the upcoming Valencia GDE meeting in November. Following that meeting, we will make some final decisions for the RDR and begin the process of concluding this phase of the design effort. Our plan is to release the draft Reference Design Report and Preliminary Costing on the time scale of the GDE Meeting in Beijing in February 2007.
