对J-PARC中微子实验质子束线的第一个全尺寸磁体系统和低温恒温器进行了磁场测量。在测量系统中，探头相对于磁体中心轴的位置由氦氖激光器和位置敏感探测器PSD测量，以获得精确的偶极场强。分析了磁场对PSD信号的影响以及PSD失调引起的误差。通过探头位置补偿偶极子分量，使偶极子分量测量值接近设计值。最新的束流模拟结果表明，磁场测量值足以满足初级质子束流输运的要求。
Magnetic field measurements have been performed for the first full-scale magnet system assembled with the cryostat for the J-PARC proton beam line of neutrino experiment. In the measurement system, the probe position with respect to magnet central axis is measured by a Helium Neon laser and a position sensitive detector, PSD, in order to obtain an exact dipole field strength. Errors associated with the PSD misalignment and influences on the PSD signals by the magnetic field were evaluated. The measured dipole components approached to the design values by compensating those with the probe position. The latest beam simulation indicated that the measured values of magnetic field were good enough for the primary proton beam transport.
