ISIS sited at the Rutherford Appleton Laboratory (RAL) is the worlds most powerful pulsed neutron source. Intense pulses of neutrons are produced at 50 Hz when a heavy metal target is bombarded with a beam of high energy (800MeV) protons. Energy is imparted to the protons by accelerating them in a synchrotron, the magnets of which are connected in a configuration known as a White Circuit*. This White Circuit suffers from problems arising from drifting values of capacitance and inductance which affect the resonant frequency. This paper focuses on the design, simulation, and implementation of a solution utilising Static VAr technology to regulate the resonant frequency of the White Circuit.
