Below is the White Circuit Schematic figure which is used in the booster synchrotron. The following file will summarize
you with informations regarding the operation performance
of the White circuit and to make the White circuit magnet current
controllable. The aim is that it will help to find the strategy for
reducing the fluctuation of the beam current.
Accordingly, the booster synchrotron
consist of three families of magnet systems (dipole, the focusing
quadrupole and the defocusing quadrupole magnets) with 12 magnets for
each of those group. In the White
Circuit, two coupled resonant circuits comprise the circuit with A
bypass capacitor and a DC power supply connect two resonant LC circuits.
Each White circuit is excited by an IGBT based DC and AC power supply, which are independent power supply souces.
Another sections you can find in this article discuss the field regulation, Current and phase regulation loop of the AC power supply schematic diagram, performance of the measurement system, Current Stability of the White Circuit, and Phase Tracking Stability of the White Circuit.
