Abstract :
Performance of a 4.6 m-long drift chamber filled with a CO2 iso-butane (90:10) mixture was studied using cosmic-ray data, in the course of detector R&D for JLC. After correcting the data for wire displacements due to gravitational and electrostatic forces, a spatical resolution of 100 μm per wire was achieved over the full length of the chamber. The relation between wire efficiency and oxygen remnant in the chamber gas is also discussed.
