摘　　要：理论计算了采用热释光剂量计 ( TLD)监测不同能量 ( 1 4～ 32 Me V)的质子注量灵敏度 ,在 35Me V质子加速器上利用 TLD对质子注量进行了监测 ,并将结果与法拉第筒所测注量进行了比较 ,证明采用The article determines the sensitivity of measuring proton(14 32MeV) fluence using thermoluminescence dosimeters(TLD) on theoretical grounds and performs the experiment research. The components, dimensions and dosimetric properties of the TLDs used in this experiment are described. The energy losses, absorbed doses and proton influence sensitivities are calculated on the theoretical grounds. Two types of TLDs are used for measuring the proton fluence on 35MeV proton accelerator. The scattering beams are acquired by gold foil. The proton fluence uniformity of identical scattering distance and angle are measured using TLDs. The proton fluence nonuniformity of identical scattering distance and different scattering angle are also measured by TLDs. The proton fluence nonuniformity ratios of different scattering angle measusred by TLD agree with the theoretical value.The measured data are compared with Faraday cup's data and the results show agreement with estimated uncertainties (±10%).This paper demonstrates that the proton fluence measured by TLD is accurate.
