在完成νμ→ντ振荡搜索的数据采集后，CHORUS铅闪烁体量热计在1998年的运行中被用作活动靶。在CERN SPS西区中微子束中收集了带电电流相互作用的高统计样本。这个束主要包含来自符号选择的π介子和K介子的μ介子（反）中微子。我们测量了入射中微子的通量和能谱，并与束流模拟结果进行了比较。在0.01<x<0.7，0.05<y<0.95，10<Ev <200 GeV范围内测量了中微子-核子和反中微子-核子微分截面。我们提取的中微子-核子结构函数F2（x，Q2），xF 3（x，Q2），和R（x，Q2），并比较这些与其他实验的结果。
After completion of the data taking for the νμ→ντoscillation search, the CHORUS lead–scintillator calorimeter was used in the 1998 run as an active target. High-statistics samples of charged-current interactions were collected in the CERN SPS west area neutrino beam. This beam contained predominantly muon (anti-)neutrinos from sign-selected pions and kaons. We measure the flux and energy spectrum of the incident neutrinos and compare them with beam simulations. The neutrino–nucleon and anti-neutrino–nucleon differential cross-sections are measured in the range 0.01<x<0.7, 0.05<y<0.95, 10<Eν<200 GeV. We extract the neutrino–nucleon structure functions F2(x,Q2), xF3(x,Q2), and R(x,Q2) and compare these with results from other experiments.
