Abstract
The calibration of two types of an electrostatic beam position monitor was carried out. Signals from the electrodes are converted into beam coordinates using a nonlinear polynomial transformation, the coefficients of which are calculated using the least squares method. This made it possible to measure the position of the beam with an accuracy better than the required value of 0.1 mm for a single passage of the beam. The mechanical center of the monitor has been linked to external geodetic signs. The calibration result was used with all monitors in the ring based on the assumption that they were all manufactured to the same mechanical accuracy. This made it possible to measure beam parameters with better accuracy than before calibration.
期刊介绍：
Instruments and Experimental Techniques is an international peer reviewed journal that publishes reviews describing advanced methods for physical measurements and techniques and original articles that present techniques for physical measurements, principles of operation, design, methods of application, and analysis of the operation of physical instruments used in all fields of experimental physics and when conducting measurements using physical methods and instruments in astronomy, natural sciences, chemistry, biology, medicine, and ecology.
