SIS100 Roadmap Contradictions A.Stafiniak at el. 1.12.2010

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 A.Stafiniak at el. 1.12.2010 * ‘All systems which were not tested in LHC Strings failed!’

SIS100 Testing Scenarios vs. Schedule B A.Stafiniak at el. 1.12.2010

Topics to be discussed Testing strategy in given conditions. Testing 100% or only 20-40% magnets (units) at cold. Testing 0…100% of components at cold. Recommended number of spare components vs. chosen strategy. String SIS100 as a Quality Assurance milestone. Recommended strategy for String SIS100. A.Stafiniak at el. 1.12.2010
