Purpose of the Z stopper Function of the Z stropper – Position along Z the IBL package respect to the IST – Guaranty that once engaged, the package can not extract – But is shall allow disengagement for the extraction process – Orientate angularly the package Constrain in the design – Limited space to position this Z stopper – Made out of material with low X/Xo Can withstand activation of the area With high enough elasticity 29/09/201111

IBL package characteristics IBL package weight : – about 20kg (to be re-evaluated) Friction coefficient between IBL package and IST : – to be measured (this operation can be done at cern as we have IST with some peek interfaces 29/09/201112

Work to be done Step 1 – Fabricate a prototype out of a titanium plate (1.5mm) – Fabricate a test bench to measure insertion/extraction force – Test : Measure the insertion/extraction force Evaluate if the extraction with cables are helpful – Loop on the design to modify geometrical parameters Step 2 – Fabricate a second prototype out of a titanium plate – Test : Measure the insertion/extraction force – Loop on the design to modify geometrical parameters Step n – Make a prototype out of a titanium block – Test : Measure the insertion/extraction force Validate the design Install this block on the integration mock-up at CERN – Validate integration – Validate the positioning precision – Validate the insertion/extraction force 29/09/201113
