- Abstract:
- Synchrotron particle accelerators are mainly composed of magnets. Long dipole magnets are employed to bend and to contain the beam within a circular trajectory. Their field quality is usually tested by arrays of rotating coils. Typically the measurements must be affected by low uncertainty (±10-4) and the calibration of the sensing coils, in terms of surface and angle, is critical. In this paper, a new method for the coil calibration is presented. The method is firstly stated formally and then validated in an actual use case. Experimental results demonstrate the capability of the method to meet also constraining requirements.
