14. Claude SANZRequirements and characteristics of the Φ0.1mm CuBe wire C ONCLUSION The wire reflects more in infrared than in visible light The test for the strength is not well adapted to this wire The wire is neither regular along its length (diameter) nor around itself (roughness/form) -> The sensor I will choose may need to be spinning… (Sensor or wire?) Not all the irregularities are part of the wire -> A way of cleaning the wire must be found before using it for the final measurements The roundness must be measured… -> I will contact a colleague of my accademical supervisors’ to get help -> We might have a mount which could be adapted in the metrology lab The magnetic measurements and the electric measurements are to be done… -> Any idea?
