主 题:Particle tracking detectors Vertexing algorithms Pattern recognition cluster finding calibration and fitting methods Time projection chambers
摘 要:This work proposes a fast method of vertex reconstructing for incident ions in GEM detectors. Inspired by the Time Projection Chambers (TPC) approach, the time information of consecutive signal samples from Front End Electronics (FEE) is utilized. The method is demonstrated with a 2D-readout THGEM detector coupled with an APV-25 FEE. Using only one experimentally dependent parameter in the analysis, the proposed method resulted in a spatial resolution of 0.45 mm, compared to a value of 9.10 mm for the traditional center of gravity method.
