Investigation of the operation of Thick Gas Electron Multiplier and Electron Multiplier Assembly for alpha particle detection
In this study, the detection of alpha particles in the high current mode is investigated in the presence of two gaseous electron multipliers in the micro-pattern structures. Thick Gas Electron Multiplier (TGEM) and an Electron Multiplier Assemblies (EMA) were designed and constructed as amplification gap in the detector chamber. An ion chamber is employed to measure the current of interaction b...
متن کاملSealed Gas UV-Photon Detector with a Multi-GEM Multiplier
A sealed gas photon detector with a GEM (Gas Electron Multiplier) cascade coupled to a semitransparent CsI photocathode has been studied. High gains, reaching 10, and fast anode signals, of a width of 15 ns, were obtained with this GEM-Photomultiplier in Ar/CH4 (95/5), in a photon counting mode. The life-time of this first prototype detector under high photon flux and large anode currents is pr...

متن کاملA How-to Approach for a 3d Simulation of Charge Transfer Characteristics in a Gas Electron Multiplier (GEM)
In this paper a detailed description of how to simulate charge transfer processes in a gaseous device is presented, taking the Gas Electron Multiplier (GEM) as an example. A 3-dimensional simulation of the electric field and avalanche is performed. Results on charge transport are compared to experiment and agree within experimental errors; avalanche mechanism and positive ion feedback are studi...
متن کاملSingle Electron Detection with GEM
Sensitivity to single electrons is requested in detectors based on the electron counting technique, measuring very low radiation-deposited energies. It is also required in novel large-area gaseous photomultipliers, employing solid photocathodes and gaseous electron multipliers. The Gas Electron Multiplier (GEM) has been considered for these applications, and we report on its properties when ope...
