Abstract

We outline a physics program at Fermilab that would significantly improve our ability to understand the behavior of hadronic showers in calorimeters. This would involve a two-pronged approach designed to measure particle production cross sections of hadronic beams on several nuclei to improve shower simulation programs and the validation of the improved shower simulation predictions using test beams (including tagged neutral beams) in which calorimeter modules built using various technologies are deployed in the test beam. Such a program would be of immediate benefit to the efforts to design and build optimal calorimeters for the International Linear Collider.
