New Power Supply Control Interface and Energy Ramping in SRRC

For the purpose of lattice optimization, eighteen individual quadrupole power suppliers are scheduled to be installed in the SRRC storage ring in March, 1997, to replace the exited three quadrupple family power suppliers. In order to accomodate new and exited power suppliers, the control interface of Taiwan Light Source (TLS) has been rejuvenated recently. The new control interface has improved drastically on control speed in comparison with the existed interface. Operation of the power supply system from device level to system level is reorganized to make control and access of individual power supply happen. This new control interface provides capability for complex operation such as lattice file loading, magnet degaussing, to file energy ramping scheme, etc. Performance of this power supply control interface including hardware components and software applications will be presented in the report.
