Performance of the Ramping Power Supplies for the APS Booster Synchrotron*
نویسنده
چکیده
The Advanced Photon Source (APS) booster ramp cycle is completed within 250ms and repeated at 2Hz. Separate phasecontrolled power supplies deliver current to each of the dipole, quadrupole, and sextupole magnet families. Tracking requirements are particularly challenging because of the fast (non-resonant) ramp. In order to meet the requirements, both conventional regulation and cycle-to-cycle adaptation are used. The power supply system and its performance are described.

An Overview of the Aps 352-mhz Rf Systems
The Advanced Photon Source (APS) is a 7-GeV full energy positron storage ring for generating synchrotron radiation with an injector. The booster synchrotron rf system consists of a single 1-MW klystron which drives four five-cell cavities at 352 MHz. The storage ring cavities consist of four groups of four single cells powered by two 1-MW klystrons for 100-mA operation. An overview of the opera...
متن کاملTiming System of Spring-8 Booster Synchrotron
The timing system of SPring-8 booster synchrotron generates various timing signals concerning beam injection, acceleration from 1 GeV to 8 GeV and ejection. We have improved the timing system of the synchrotron giving it better stability and flexibility. This improvement results the other merits of advanced operations, for example, storing electron beam in the synchrotron, changing the injectio...
متن کاملSynchrotron Light Monitor System for Nsls-ii
A visible synchrotron light diagnostic beam line has been designed at the NSLS2 storage ring, using the dipole radiation. The ‘cold-finger’ configuration has been selected to block the central x-rays. Beam power on the first mirror is less than 1W, no water cooling is required for the in-vacuum mirror. The beam line layout and major applications will be discussed in this paper. Two vacuum ports...

P. Bellomo, A. de Lira (SLAC) Menlo Park, CA 94025-7015, USA Abstract The Stanford Synchrotron Radiation Laboratory (SSRL) has successfully commissioned SPEAR3, its newly upgraded 3-GeV synchrotron light source. First stored beam occurred December 15, 2003 and 100mA operation was reached on January 20, 2004. This paper describes the specification, design, and performance of the SPEAR3 DC magnet...
متن کاملDigital Internal Model Control of High-precision Power Supply for Particle Accelerator Magnets
The paper presents the control of a power supply feeding a quadrupole magnet of a booster synchrotron. The supply equipment is based on a switching architecture where current sharing and interleaving techniques are adopted to minimize the voltage/current ripple. Internal model principle is exploited in the control design to guarantee extremely accurate tracking of the sinusoidal current referen...
