Final Design Review Documentation and Drawing Overview Colour coding Review documentation directly linked to file Review documentation linked to another slide Referenced documentation directly linked to file Referenced documentation linked to another slide Document change log: Pre-v1 – first draft for circulation in fibre group meeting This presentation is designed to allow one to follow the documentation path down an assembly by clicking on an item. In PDF format this will not work, but one can still navigate manually to the same place

Procedures have been tested extensively at LASTI for the prototype quadruple suspension. Document T describes bonding of the ears onto the ITM and PUM at LASTI and gives insight in the bonding of the prisms using VacSeal adhesive. The bonding of the magnet flag assemblies at LASTI is described in T080245T T E Generic bonding procedure E First Contact procedure E Jig settings calculation spread sheet
