“…Sources of electron beam position disturbances are listed in Table 1 [3,5,7,8]. Table 2 [7,[9][10][11][12][13][14][15][16][17][18][19][20][21][22][23] provides details of light sources with slow-orbit feedback (SOFB) correction systems, fast-orbit feedback (FOFB) correction systems, and hybrid correction schemes (SOFB + FOFB). Global orbit feedback systems include BPMs, corrector magnets, and a circuit-controlled algorithm to obtain an orbit response matrix (ORM).…”

“…A typical FOFB bandwidth is in the order of 100 Hz. Nevertheless, SIRIUS [12] achieved a 1 kHz bandwidth using a 0.5 mm lamination core. The fast-corrector magnet at the ESRF [7] obtained a DC to 500 Hz bandwidth via iron-core lamination.…”

A prototype of a combined horizontal and vertical correcting magnet was designed and fabricated for the 3 GeV storage ring of Siam Photon Source II, which will be the second synchrotron light source in Thailand. The magnet will be employed for fast-orbit feedback correction, with a required magnetic field integral of approximately 8 Tesla.mm. The magnet pole and yoke were manufactured using laminated silicon steel to minimize hysteresis and eddy current losses during operation. Magnet modeling and magnetic field calculations were performed using Opera-3D. The size of the gap between the magnet poles is limited by the size of the vacuum chamber over which the magnet will be installed; in this case, it was designed to be 65 mm. Mechanical analysis of the structure of the magnet was performed using SOLIDWORKS and ANSYS. Magnetic field measurements were obtained using the Hall probe technique. The entire prototype, from its design to manufacturing and measurement, was completed in-house. This design will be appropriate for application at the Siam Photon Source II storage ring.
