Reinhard Bacher HERA technical coordinator DESY Notkestr.85 22607 Hamburg Germany e-mail: bacher@desy.de Abstract: (offered as either oral or poster ...FWB)) **************************************************************** Maintenance, Documentation and Operator Training at the DESY Accelerators R.Bacher, Deutsches Elektronen Synchrotron (DESY) The DESY accelerator complex consists of a couple of different pre-accelerators of linac- or synchrotron-type which not only feed the HERA (high energy electron/positron versus proton) collider but also the DORIS positron storage ring used for synchrotron light studies. A review of the maintenance strategies and the training efforts for the operator crew will be presented. A novel Electronic Document Management System (EDMS) to store descriptions of operating procedures as well as information about technical systems is currently being introduced at DESY. The initial experience gained using the EDMS will be reported. ********************************************************************
