1. A power supply for a photomultiplier, the power supply comprising:
a charge pump configured to generate a first high voltage for the photomultiplier;
a DC/DC converter configured to generate a second high voltage for the charge pump;
a first control loop configured to control the charge pump, wherein the first control loop is controlled by the first high voltage; and
a second control loop configured to control the DC/DC converter, the second control loop being controlled by the second high voltage.
