监测FNAL的NuMI中微子束流的离子室
Ion Chambers for Monitoring the NuMI Neutrino Beam at FNAL
摘要：
主注入器（NuMI）光束线处的中微子将通过将一束介子聚焦到一个长的真空衰变体积中来提供强烈的μ介子中微子束。波束必须以1 mRad的角度精度转向明尼苏达州北部的苏丹地下实验室。我们已经建立了4个阵列的电离室监测中微子束的方向和质量。该阵列位于衰变体下游的4个站点，并测量介子衰变中伴随中微子产生的剩余强子束和第三μ子。我们将审查如何使用监视器进行光束质量测量，以及我们审查室的建设细节，辐射损伤测试，校准和测试光束的结果。
英文摘要：
The Neutrinos at the Main Injector (NuMI) beamline will deliver an intense muon neutrino beam by focusing a beam of mesons into a long evacuated decay volume. The beam must be steered with 1 mRad angular accuracy toward the Soudan Underground Laboratory in northern Minnesota. We have built 4 arrays of ionization chambers to monitor the neutrino beam direction and quality. The arrays are located at 4 stations downstream of the decay volume, and measure the remnant hadron beam and tertiary muons produced along with neutrinos in meson decays. We review how the monitors will be used to make beam quality measurements, and as well we review chamber construction details, radiation damage testing, calibration, and test beam results.
