英文摘要 | The performance of a fine-mesh photomultiplier tube (PMT)-Hamamatsu R5924(FM) to be used for the time-of-flight (TOF) counter in the upgraded Beijing Spectrometer (BES III) was investigated in a strong magnetic field up to IT. The dependence of the PMT relative gain on the magnetic field intensity at both 0degrees and 180degrees directions were measured. It was found that the relative gain of the PMT is reduced by a factor of 50 or more at IT magnetic field compared with no field case. The relative gain of the PMT vs. the working voltage at different magnetic field intensities (0, 0.5, 1 T) were also measured. An exponential dependence of the relative gain on the working voltage was observed for a wide range of the working voltage. Moreover,the factor k in the secondary electron emission ratio 8 is measured to be less than the nominal value due to the special fine-mesh structure of PMT's dynodes and it decreases with the increasing magnetic field intensities. It is the important reason that the gain of PMT decreases in case of strong magnetic field existence. |
