Abstract
The response of the Hydrostatic Leveling System (HLS) for the final focusing quadrupole magnets in the Large Hadron collider is dose rate dependent. At high dose rates, ionization of the air inside the sensors causes charge deposition and this perturbs the position measurement. A model is presented that corrects the HLS signal offset as a function of the dose rate.
