26. fabrizio.rossi@cern.ch 26 Thermal tests planning for mock-up TM0 6. MEASUREMENTS Measuring arm Romer Multi Gage With a length of 60 cm, this kind of portable CMM allows to measure fiducials by probing or by one point. According to Romer, the maximum permissible error is less than 18 µm. Laser tracker Leica AT401 According to simulation calculations, the expected accuracy of AT401 measurements on a girder and its components is about 5 µm rms (up to 40 °C). Fiducials are measured with respect to a fixed reference system. Measurements taken from different stations can be elaborated and combined together. The measuring device must be at the same temperature of the parts to be measured. Micro-Triangulation system The principle of Micro- Triangulation is to use the full potential of a theodolite by substituting a CCD camera instead of the eye of an operator. This method has clearly demonstrated its high precision capability on the 2 m long mock-up where a precision about 10 µm along each axis has been obtained in the determination of the illuminated fiducials locations. Fiducials dedicated to Micro-triangulation The aluminium main part of this fiducial (made in CERN) is equipped with a breakthrough ceramic ball with a diameter of 8 mm, a removable drawer which contain a LED allows to illuminate the accurate ball.
