Electrons and positrons travel several tens of kilometres nearly at the speed of light, needing to stay on course as they zoom through various components of the machine. How, you ask? Electrons have a negative charge and positrons have a positive charge, and moving charges receive forces in the magnets when they travel in magnetic fields. In the International Linear Collider, there will be about 17,000 magnets – and knowing precisely all of their field properties is the key to success for beam control. A challenge arises, however, because some of the ILC magnets are extremely hard to measure – 1 metre long magnets with an aperture of only 12 milimetres.

Feature Story
Fermilab ILC Task Force Evaluates How to Increase Future Participation and Collaboration with University Community

The ILC Test Area - Meson Detector Building is one of the new facilities that will help Fermilab's user community participate in R&D activities.
As time marches closer to making a decision on siting and building the International Linear Collider, the number of scientists working on the project will have to dramatically increase. From the graduate student to the senior physicist, large numbers of scientists will have to be recruited to design, build and eventually operate the machine. Over the past year, particle accelerator schools have taught new students about the ILC, but other efforts beyond the classroom are also happening, such as Fermilab's ILC Task Force.

Feature Story
Fermilab and Argonne Host Next LCFOA Meeting

LCFOA President Ken Olsen
The Linear Collider Forum of America, a not-for-profit industrial forum , will hold their fall 2006 meeting on 16-17 October. The meeting will start at Argonne on the afternoon of Monday 16 October and will continue all day Tuesday 17 October at Fermilab.

Following the last LCFOA meeting at SLAC in May, this next session will focus on progress made by the ILC program over the last several months, cavity and surface polishing R&D at Argonne and an opportunity to tour the new ILC facilities being developed at Fermilab. Industry members will have the opportunity to provide feedback and recommendations on needed user facilities and such issues as manufacturing, scheduling and contracting during a panel discussion at the end of the meeting. There will also be a smaller, detailed technical workshop for companies interested in magnet manufacturing on Wednesday 18 October.

Director's Corner
The Evolving ILC Design: Changing the Crossing Angles
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. Changing the crossing angles for the final focus interaction regions is one item that has been under discussion for some time now.

Andre Seryi, a task leader for ILC Beam Delivery Systems
Last fall, we adopted an ILC baseline that had two beam lines -- one with a crossing angle of 2mrad and the other with 20mrad. The design of the resulting beam delivery system staggered interaction points in two separate detector halls. Motivated by the significant cost savings, as well as lower risk, we recently decided to change the beam line configuration to having two beam lines with 14mrad crossing angles. It is a particularly notable change, because of the potential physics impacts, which had to be weighed against the cost savings and lower risk.
