The quadrupole magnet power supply PLD250-DAL110 comes in two specifications: thin quadrupole iron and thick quadrupole iron. Their main function is to focus the protons in the electron beam, enabling the protons to perform linear acceleration motion. They only differ in the degree of focusing, and ultimately both aim to prevent protons from deviating.

The ScanU scanning power supply PLD25K-DAL101 for the treatment head provides appropriate excitation current for the scanning magnet, enabling precise deflection of the beam. It has extremely strict requirements for the stability, regulation accuracy, and dynamic response capability of the output current.

The Abort Kicker Magnet Power Supply mainly provides excitation current for the corresponding magnet. The operating current of the magnet power supply works at a set value or zero, and is controlled by timing synchronization pulses. There are physical requirements for the speed of its rise, fall and jump.
