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.
