Advantages of platform for push-pull operation
• The use of a platform is well adapted to ILD sectioning and construction.
• With the use of airpads and indexing system, this should allow a millimetric repositioning.
• The presence of the platform can be taken advantage of to isolate the experiment from seismic events and from surrounding vibrations.
