Abstract

The possibility of geometrical deformations of the anode planes of the OPAL jet chamber has been investigated. Using an UV laser beam, which passes through the chamber under various well-known angles {Theta} wrt the symmetry axis, possible deformations can be determined from studies of the track sagittae as function of the angle {Theta}. A small torsion of the detector end cones has been found, resulting in a displacement at outer radii of about 100 {mu}m. The deformations of the suspensions of the anode wires are smaller than about 20-30 {mu}m. The extra error of the transverse momentum due to geometrical deformations is {sigma}P{sub t}/P{sub t} {approx_equal} 3% for momenta of 45 GeV/c and a magnetic field of 4.35 kG. (orig.).
