Construction of a Drift Chamber with Very High Resolution

For the electronic measurement of the decays of the new particles one would like to have a drift chamber with as high a space resolution as possible. Known critical factors are a. the primary ionisation density b. the widening of the tracks due to the range of the knock-on electrons c. the diffusion of the drifting electron in the direction of drift d. the homogeneity of the drift field e. the mechanical accuracy f. the accuracy in timing.
