Abstract The L3 detector is designed to measure the muon momentum with a 2% resolution at p = 45 GeV/c. We discuss here the systems we developed to reach the required accuracy and control the mechanical alignment at running time. We also report on the test done on the muon spectrometer with UV lasers and cosmic rays.

Abstract A drift chamber which measures the drift time of photoelectrons emitted from the cathode surface by means of a UV laser pulse has been built. The chamber is used for monitoring the drift time changes in the muon chambers of the L3 detector at CERN due to changes of gas parameters with the accuracy of 0.1%. The construction and experiments to determine the accuracy and stability of the device are described.

Abstract We describe test results on the operation of a time projection chamber incorporated into a Cherenkov counter to track a particle while it is emitting its Cherenkov light. The common Cherenkov and drift chamber medium is high-pressure hydrogen. The ring-imaging counter detects and digitizes Cherenkov photons by means of an image-intensifier and matrix-camera. The TPC measures the particle trajectory without obscuring the Cherenkov light. In a beam of 5.4 GeV/c pions, the particle direction is determined to within 82 μ rad and the particle velocity to within 9 ppm.
