WebThis low emittance lattice structure has strong quadrupoles and sexturpoles. Therefore, the magnet misalignment will introduce large closed orbit distortions (COD) which induce unwanted side effects. In section 2, the closed orbit distortions due to magnetic errors are simulated and the efficiency of correction scheme is proposed. WebFor low-emittance storage ring design, we made effort to minimize the integral quantity . Most 3GSR rings have adopted DBA lat-tice [3] or TBA [4] as lattice option (Fig. 2). ... (ID FF) [13], and fast orbit feedback implemen-tation, orbit stability has been achieved within several microns per day up to 100 Hz motion. As mentioned above ...
The low emittance requires a stable electron beam orbit that is < 10% of the beam size, in the submicron range. Since the facility was commissioned in 2015, a fast orbit feedback (FOFB) system has been implemented. This system is used to suppressed noise at DC to a few hundred Hz. WebColucci’s Jewelers. 15.
