| The project of free electron laser is worked together completed by CAEP(Chinese Academy of Engineering Physics）and IHEP(Institute of High Energy Physics, China). Conventional magnet of the project includes a total of three deflecting dipole magnet, an analysis of dipole magnet, and two quadrupole magnets. All of magnets to complete the measurement by IHEP Hall measuring equipment. The measurement trajectory of integral magnetic field for deflection dipole magnet is arc and arc tangent direction, using Labview software written a new measurement procedures, the Hall probe directly read absolute value of the three-axis(X, Y, Z) coordinate point (relative to the Hall probe in terms of absolute zero) measurement functions, Not only achieve the purpose of measuring the trajectory can be freely combined, but also effectively eliminate the accumulated error of Hall mobile devices. All measurement results of conventional magnets have reached the physical design requirements, and each magnet were carried out more than twice the measurement, the reproducibility of the measurement results are better than one-thousandth, fully meet the design claim of CAEP. | ||

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.
