International Linear Collider

Mark Thomson (Cambridge University)

The ILC e+e- collider is being designed to operate in the centre-of-mass range 0.5-1.0 TeV. The ILC physics programme of precision measurements places stringent requirements on the detector performance. Of these requirements the goal of a jet energy resolution of 30%/sqrt(E) is probably the most challenging. It is widely believed that particle flow calorimetry is the most promising approach to meeting this goal. In particle flow calorimetry the energy deposits from individual particles are identified. Particle flow calorimetry requires highly granular calorimeters and plays a major role in the design of a detector for the ILC. In this seminar I will describe the ideas behind particle flow calorimetry and discuss its impact on the current conceptual detector designs.
