This document discusses instrumentation solutions suited for use in magnetic fields of 8,5 Tesla by the example of a robot probe built for CERN's Large Hadron Collider LHC. The probe will measure and analyze the magnetic field topology inside dipole and quadrupole magnets of up to 15 m length, through an open aperture of Ø50 mm. Solutions for rotating and linear drives, for rotation and position encoding, for inclination sensing and for the actual magnetic field analysis are discussed. Suitable materials and the field-compatible geometry applicable in each case are examined. Furthermore, a selection of optical position and alignment measuring techniques suitable for high magnetic fields is presented and evaluated. A modified alignment measuring telescope was identified as an adequate solution for the lateral position detection of a probe inside a magnet.
