Abstract:
A model of pictorial drift chamber is constructed. The associated readout circuit of the model chamber is made with the capability of recording 8 hit events. The present study was undertaken to investigate the properties of the chamber, including spatial and double track resolutions, resolution of left/right ambiguity, as well as the pattern recognition of multi-track events. In this paper, the construction of the model chamber is briefly described. Also described are the principle and the block diagram of the readout circuit, the properties of each unit, as well as the properties of the whole circuit. The experimental results reported here include X-spatial resolution (σx=280μm), Z-spatial resolution(σz=3cm), and the reconstructed track picture of a cosmic ray shower.
