Abstract :
The manufacture and testing of multicell limited streamer chambers for use in the hadron calorimeter of the OPAL detector and LEP (Large Electron Positron Collider) are described. All operations, from chamber cathode coating to the testing of completed subassemblies, have been performed under the same roof. With reasonable care and quality control, the established technology produced chambers several meters long with an overall success rate of about 90%. Treatment of the carbon coating with Breox B-35 was effective in eliminating uncertainties in the cathode performance
