Embodiment Construction

[0041] figure 2 It is a schematic diagram of a rectangular electrode of the rectangular electrode unit of the position-sensitive anode of the present invention. Two sinusoidal insulating channels with the same period and amplitude divide the rectangular electrode into three strip electrodes, the widths of which are A1, A2 and A3 (see figure 2The proportional relationship of the vertical dotted line in ) changes periodically along the measurement position direction X. Therefore, the proportional relationship of the panel areas ΔS1, ΔS2, and ΔS3 of the three strip electrodes also changes periodically along the direction of the measurement position. Therefore, when the charge cloud covers the three strip electrodes, the periodic position of the charge cloud center of mass can be calculated according to the proportional relationship of the charges collected by the three strip electrodes. This is one of the basic ideas of the anode decoding of the present invention. The change...

Abstract

The invention relates to a high-resolution position-sensitive anode detector and an anode decoding method thereof, which belong to the technical field of multi-anode detection. The invention provides the electric charge dividing type high-resolution position-sensitive anode detector and the anode decoding method thereof, which have the advantages of extremely high resolution, little image twisting and unlimited anode panel design area. The invention aims at overcoming the defects of complicated read-out circuits and limited anode panel design area of the existing multi-anode detector. The multi-anode detector and the anode decoding method thereof of the invention can realize position measurement and counting imaging of other particles such as photons, electrons and the like, and can be applied to the scientific technical fields such as deep space detection, nuclear radiation and ion detection, biological super faint imaging, quantum communication and the like.

Description

technical field [0001] The invention relates to a position-sensitive anode detector and an anode decoding method thereof, belonging to the technical field of multi-anode detection. Background technique [0002] Compared with solid sensors such as CCD, CMOS and CID or coupled image sensors such as ICCD and EBCCD, multi-anode detectors have the advantages of high signal-to-noise ratio, good drift resistance, and wide dynamic range, so they have been widely used in deep Space detection, nuclear radiation and ion detection, biological ultra-weak imaging and quantum communication and other scientific and technological fields. Multi-anode detectors can be divided into two types: impedance type and charge division type. The impedance type produces different electrode output signals according to the different electrode impedances at different positions for event decoding. Due to the relationship between position decoding and electrode impedance, thermal charge noise will limit its ...
