Position Sensing by Charge Division

Position Sensing

A summary of a comprehensive analysis of theoretical and practical aspects of position sensing by charge division from resistive electrodes is presented. Properties of transformer decoupling of the resistive electrode from detectAi bias voltage are analyzed and compared to the usual capacitive decoupling methods. Optimization and limitation of signal shaping is discussed as a function of diffus...

2D position sensitive microstrip sensors with charge division along the strip_ Studies on the position measurement error

Position sensitivity in semiconductor detectors of ionizing radiation is usually achieved by the segmentation of the sensing diode junction in many small sensing elements read out separately as in the case of conventional microstrips and pixel detectors. Alternatively, position sensitivity can be obtained by splitting the ionization signal collected by one single electrode amongst more than one...

Position Sensing with Photodiodes

Position sensing photodiodes are detectors that provide quantitative information about the position of an incident light beam or spot image. There are currently two technologies that offer this functionality: multi-element photodiodes and position sensing (or lateral displacement) photodiodes. This article reviews the construction and operation of both types, discusses key considerations for op...

Position Sensing from Charge Dispersion in Micro-Pattern Gas Detectors with a Resistive Anode

Micro-pattern gas detectors, such as the Gas Electron Multiplier (GEM) and the Micromegas need narrow high density anode readout elements to achieve good spatial resolution. A high-density anode readout would require an unmanageable number of electronics channels for certain potential micro-detector applications such as the Time Projection Chamber. We describe below a new technique to achieve g...
