Critical Design Review Personnel Safety System: PSS0 www.europeanspallationsource.se 2018-02-08

Introduction Ion Source/LEBT Test Stand ESS follows a staged installation and commissioning plan Ion Source and LEBT (made in Catania/INFN) have arrived in Lund and are currently installed 1st step is to operate the Ion Source and LEBT as “test stand” safely

Introduction PSS0 PSS0 is the electrical safety system for the Ion Source and LEBT test stand Mitigation against electrical hazards is implemented by switching off the HV PS (90kV) of the Ion source HV platform Installation is prepared to start on 2018-02-12 (rack installation, cable termination, etc) Scope is restricted to electrical hazards. Radiation hazards (prompt ionising radiation/not activation) are mitigated by shielding the areas where dose levels might exceed >2microSieverts/h with lead. Prompt radiation hazards are mitigated also indirectly by switching off the HV PS of the Isrc (no power, no beam)
