Study of Energy Saving Operation for the TLS Booster Power Supply

Operating an injector of a synchrotron light source, energy efficiency is an important issue. Dipole and quadrupoles families of the booster synchrotron for Taiwan Light Source (TLS) is resonantly excited by three White circuits at 10 Hz rate. Magnet current cannot response in cycle-by-cycle basic due to resonance nature. The possibility of operation of the booster synchrotron in energy saving mode is explored. Minimizing the duration of magnet excitation without effect of the injected and extracted beam to support top-up operation for the TLS is investigated. Efforts will be presented in this report.
