E3 - EXPERIMENTAL APPROCHES:

LINEAR COLLIDERS


Sub-Group: LC Detectors - Concepts and R&D


Coordinators: M. Breidenbach (SLAC), C. Damerell (RAL), T. Tauchi (KEK)


Charge to the Sub-Group
  1. What LC detector requirements/designs are beyond the current state of the art? What R&D is required?
  2. What are the physics cases that drive truly superb jet energy resolution? What W and Z mass resolutions are realistically possible? How rapidly does the physics improve with the resolution?
  3. What are the physics cases that drive superb vertex resolution? How does the physics performance vary with the radius of the first layer, the thickness per layer, and the point resolution? What are the pros and cons of the various technologies being considered for the vertex detector? What performance can be expected for each technology? How much R&D is required for each approach?
  4. How large are the systematic errors likely to be in aligning the tracking systems? Will they limit momentum and impact parameter resolution? Are special measures required for alignment?
  5. What R&D is required for each of the following ancillary systems: a. Polarimetry b. Energy Measurement c. Differential Luminosity d. Instantaneous Luminosity
  6. Compare the Tesla and NLC/JLC environments from the standpoint of the various detector elements.
