A fast spatial resolution optimizing method for track-ion using a GEM detector based on the time information
Abstract
In this work, a fast method of vertex reconstructing for incident ions in GEM detectors was proposed. As inspired by the Time Projection Chamber (TPC), the time information of the consecutive signal samples from Front End Electronics (FEE) was employed. To demonstrate the method, an experiment involving a 2D-readout THGEM detector with an APV-25 FEE was taken. With one experiment dependent parameter in the analysis, the proposed method led to a spatial resolution of 0.45 mm, compared with the same number of 9.10 mm from the traditional center of gravity method.
