Electrostatics of Wire Grids and Field Cages
The electric field in a drift chamber must provide two functions: drift and amplification. Whereas in the immediate vicinity of the thin proportional or ‘sense’ wire the cylindrical electric field provides directly the large field strengths required for charge amplification, the drift field must be created by a suitable arrangement of electrodes that are set at potentials supplied by external voltage sources. It is true that drift fields have also been created by depositing electric charges on insulators — such chambers are described in Sect. 10.4 — but we do not treat them here. Also, charge amplification is not necessarily confined to proportional wires — the parallel-plate chamber is discussed in Chap. 13.
