| THPMW006 | The Realization of the System for Rapid Detection of Bepc Ii Magnet Power Supply | 3543 |
|
||
| To quickly find the causes of the accelerator unstable or lost beam caused by magnet power supply in the Beijing Electron Positron Collider running, this set of rapid detection system for magnet power supply is developed. The stability of the system in 8 hours is about 0.005%, it can acquire over nearly 500 sets of magnet power supply current value most quickly in the 0.33ms time. All data is written to the MySQL database in real time，So as to be able to quickly troubleshoot magnet power supply problem through historical data analysis of database comparison. | ||

| THPMW007 | The Design of a New State Space Digital Power Supply Prototype | 3546 |
|
||
| Based on system identification and DLQR methods, a self-adaptive power supply can be implemented by the new controller structure without any change in power main circuit. Now only some raw tests have been taken which show its stableness, but the State Space Digital Controlling may turned out to be with potential. It makes power supplies with different capability easy to interchange without any more effort on tuning their parameters according to their loads, and can be extended to accommodate MIMO systems. | ||

Quench detection system is a key component of the quench protection system for superconducting magnets. According to operating experience of the quench protec-tion system for BEPCII interaction region superconduct-ing magnets and study in depth on the development process of System-on-Chip, we are establishing a set of digital quench detection system with high integration density and favourable portability by integrating IP cores, custom modules and developing embedded soft-ware on one piece of FPGA chip (Cyclone V SX SoC). The main components of this system are: 1.Hard proces-sor system based-on ARM Cortex-A9 architecture inte-grated with embedded operating system (Linux).2.Floating point DSP based-on soft IP core.3.Function Module Portion designed for different functions such as communicating with front end ADC, timing control, etc. This paper introduces the research progress of the system.
