Hybrid tracking detector based on semiconductor and gas technologies

The gas proportional scintillation counter / microstrip gas chamber hybrid detector

The gas proportional scintillation counter/microstrip gas chamber (GPSC/MSGC) hybrid detector for X-ray spectrometry is described. The detector uses a CsI-coated microstrip plate placed in direct contact with the gas-filling as the photosensor readout for the GPSC scintillation substituting for the photomultiplier tube (PMT). Usable photosensor maximum gain is limited by optical positive feedba...

Multiple Target Tracking in Wireless Sensor Networks Based on Sensor Grouping and Hybrid Iterative-Heuristic Optimization

A novel hybrid method for tracking multiple indistinguishable maneuvering targets using a wireless sensor network is introduced in this paper. The problem of tracking the location of targets is formulated as a Maximum Likelihood Estimation. We propose a hybrid optimization method, which consists of an iterative and a heuristic search method, for finding the location of targets simultaneously. T...

A Hybrid Face Detector Based on an Asymmetrical Adaboost Cascade Detector and a Wavelet-Bayesian-Detector

In this paper is proposed a hybrid face detector that combines the high processing speed of an Asymmetrical Adaboost Cascade Detector with the high detection rate of a Wavelet Bayesian Detector. This integration is achieved by incorporating this last detector in the middle stages of the cascade detector. Results of the application of the proposed detector to a standard face detection database a...

Advancements in Tracking Detector Technologies Using Novel Target Gases

This research attempts to improve upon modern gas-based tracking detectors by investigating gases unconventionally used as scintillating targets. Advancements in current technologies are vital for higher resolution track reconstruction in astroparticle physics experiments. A single-wire chamber was instrumented as a basic gas detector model and used to test CF4, N2, P-10, and C4H10. The light-t...
