Description

The ever-increasing demand for better performance from circular accelerators requires improved methods to calibrate beam position monitors (BPM). A beam based calibration system has been established to locate the centers of the BPM with respect to the magnetic center of quadrupole magnets. Additional windings are applied to the quadrupole magnets to make the quadrupole magnetic strength individually adjustable and the number of the power supply of all 32 additional windings is only one. Software system has been finished to automatically measure the offsets of BPMs. The effect of the beam-based calibration system shows that the calibration of BPM has been more quickly and accurately
