PFA Jet Measurement and Digital HCAL for the Future
International Linear Collider.

Abstract:
The physics program for the future International Linear Collider (ILC)
requires excellent (30%/sqrt(E) or 3-4%) jet energy resolution, which is
believed to be obtainable by using particle flow algorithms (PFA)
together with a highly granulized calorimeter system. In this context, I
will discuss the current status of the development of the particle flow
algorithms, the concept of digital hadron calorimetry and a viable design
for a digital hadron calorimeter with very fine segmentation, using
Resistive Plate Chambers (RPCs) as the active element.  I will also show
some preliminary results from our recent test beam of a small prototype
digital calorimeter.
