6. String Test* – Goals proving of :
stability of the local cryogenic systems (including current leads and current lead box)
integration of systems (cryogenic, electrical, electronic, mechanic)
interconnection design and assembly
mechanical stability of all systems in the string
power supply systems
functionality of the safety interlock system
proving of all control-loops behaviour
demonstrating of :
efficiency of the cryogenic system
efficiency of quench detection and magnet protection system
improving the quality assurance for :
production and commissioning (technical specification and procedures)
assembly techniques (tools and procedures)
gain experience
solving problems during commissioning
