其他摘要 | Based-MCP position-sensitive anode photon-counting imaging detector is good at detecting extremely faint light,which includes micro-channel plate(MCP),position-sensitive anode and readout,and the performances of these detectors are mainly decided by the position-sensitive anode.As a charge division anode,Vernier anode using cyclically varying electrode areas which replaces the linearly varying electrodes of wedge-strip anode can get better resolution and greater electrode dynamic range.Simulation and design of the Vernier anode based on Vernier’s decode principle are given here.Firstly,we introduce the decode and design principle of Vernier anode with nine electrodes in vector way,and get the design parameters which are the pitch,amplitude and the coarse wavelength of electrode.Secondly,we analyze the effect of every design parameters to the imaging of the detector. We simulate the electron cloud,the Vernier anode and the detector imaging using Labview software and get the relationship between the pitch and the coarse wavelength of the anode.Simultaneously,we get the corresponding electron cloud for the designing parameters.Based on the result of the simulation and the practical machining demand,a nine electrodes Vernier anode was designed and fabricated which has a pitch of 891μm,insulation width of 25μm,amplitude of 50μm,coarse pixel numbers of 5. |
