【摘要】 建立了一台图象漂移室的模型室。制作了模型室的读出线路,线路具有记录8次击中的能力。对模型室的性能作了实验研究,其中包括位置分辨、径迹的左右分辨、双径迹分辨以及多径迹事例的图象识别等。本文描述了模型室的结构特点、读出线路的原理及线路框图,给出了每个线路单元的性能指标及读出线路的总体性能。本文还给出了实验研究的结果,其中σ_x=280μm,σ_z=3cm,并给出重建簇射事例的图象。更多还原

【Abstract】 A model of pictorial drift chamber is constructed. The associated readout circuitof the model chamber is made with the capability of recording 8 hit events. The pre-sent study was undertaken to investigate the properties of the chamber, including spatialaud double track resolutions, resolution of left/right ambiguity, as well as the patternrecognition of multi-track events. In this paper, the construction of the model chamberis briefly described. Also described are the principle and the block diagram of the re-adout circuit, the properties of each unit, as well as the properties of the whole circuit.The experimental results reported here include X-spatial resolution (σ=280 μm), Z-spatial resolution (σ_z=3cm), and the reconstructed track picture of a cosmic ray aho-wer.更多还原
