R&D Items

Measurements of wire tensions and positions of a 4.6m test chamber.
Calculations of electric fields and wire distortions for cell design optimization.
Cosmic ray tests of the 4.6m chamber.
Basic chamber performance studies with a smaller test chamber (so called "baby" chamber).
Two-track separation studies with particle and laser beams.
Studies of chamber gas properties: drift velocity, diffusion, Lorentz angle.
dE/dx measurements with the baby chamber.
Wire material studies.
Development of a full CDC simulator based on Geant4 and chamber design using it.
