18. Summary URD for most sub-detectors and sub-systems Hardware
commercial solutions if possible (PLC)
common LHC solutions (ELMB)
Hardware – SCADA interfaces
commercial solutions if possible (OPC server)
Integration of Laser System
Solution to interface to Fieldcage HV PS to be studied
Solution for FEE controls depend on choice of communication
Final solution on cooling depends on prototype results
