These detectors\r\nwill be used in the future for example in FAIR facility in the Super-FRS\r\nfragmentation separator.\r\nIn this thesis, I analyze the measurements carried out by the GEM-TPC in\r\nGSI in the summer 2016 using the ROOT software. At first I will tell why the\r\nGEM-TPC detector is developed, what measurements and where it will be\r\nused. At the end of the thesis I analyze the results of the detector measurements.\r\nIn GSI the GEM-TPC detector was tested using Xe and C beams. In\r\nthis thesis, I\u2019m going to study deeper into the C beam measurements, but at\r\nthe end of the thesis I will also do an analysis of the Xe beam measurement.\r\nBased on my analysis in my thesis, the detector seems to work well and\r\nmeets some of the requirements set for it, such as performing a measurement\r\nsteadily for several days, without having to go anywhere near to it.
