Wednesday 16 April 2008 Speaker: Harry Weerts (Argonne National Laboratory) Title: The SiD detector concept Abstract: After a short introduction to the ILC, the current status of the ILC physics and detector program will be given. I will then introduce the SiD (Si based detector) detector concept for the ILC, with results from simulation on performance of the design. Areas where more effort and new ideas are welcome will be described as well.
