Abstract
A high voltage DC source for a particle accelerator is an inductively charged, coaxial nest of capacitors. The nest of capacitors comprises coaxial tubes of insulation, one inside the next, and an inductive coil. The inductive coil is wound in several layers between the tubes of insulation. The nest of capacitors is inductively charged by a high turns ratio transformer. The transformer's primary coil is wound the length of the accelerator outside the nested capacitors. The transformer's secondary coil comprises the inductive coil layered between the tubes of insulation. Diodes in series with the secondary coil produce the DC signal of the source.
Claims19
An apparatus including:
- a means for supplying a voltage signal;
- and
- a voltage multiplier that multiplies the voltage signal and includes a bank of radially arranged capacitors, the capacitors having layers which are substantially tubular and comprise an outer capacitor and at least one inner capacitor, such that the inner capacitor is nested within and surrounded by the outer capacitor, and an inductive device adjacent the radially arranged capacitors for providing an electromagnetic field which inductively charges the radially arranged capacitors.
A DC source comprising:
- cylindrical, coaxial members of insulation;
- an inductive coil which carries a first signal and is wound in layers between the members of insulation such that the inductive coil and members of insulation comprise a nested bank of capacitors arranged radially relative to one another, the capacitors having layers which are substantially tubular and comprise an purer capacitor and at least one inner capacitor, such that the inner capacitor is nested within and surrounded by the outer capacitor;
- and
- a means which is connected to the inductive coil and is positioned between members of insulation for rectifying the first signal into a DC signal.
