2 ISOLDE target unit Present target unit base at ISOLDE with 7 inlets (including ion source gas leak, heating for chimney/transfer line) Present interface at ISOLDE allows up to 4 thermocouples Changes at the front-end interface? Ion source Temperature (Multipin connnector) Chimney and transfer line heating

Temperature control Minimum 5 thermocouples needed 3 Transfer line + chimney (2x) Outlet diffusion chamber Inlet irradiation chamber Outlet Pump

Flow control 4 Inlet irradiation chamber Sensor at diffusion chamber Interlock to be included in case of flow failure – cut on proton beam - Flow rate measurement at entrance of irradiation chamber – flow meter (e.g. Venturi tube) - Pressure in the pump -LBE level in the diffusion chamber – sensor - Leak detection
