Abstract

This paper introduces the working principle of the power supplies for the septum magnets in HIRFL-CSR and presents a feasible scheme of digitalizing these power supplies. The scheme employed the SOPC (system-on-a-programmable-chip) technology based on FPGA, the software framework of NIOSII and the polycyclic adjustment algorithm realized by the hardware description language. Then, several key problems that could be encountered in realizing the power supply control algorithm on FPGA were discussed. After the power supplies were upgraded, the beam of HIRFL-CSR was extracted more reliably and the stability of beam spot position at the experimental terminals has been obviously improved. This work would provide a valuable reference for the engineers of digitalizing other magnetic power supplies in HIRFL-CSR and of developing magnetic power supplies for heavy ion cancer therapy.
