Simulation, design and construction of a gas electron multiplier for particle tracking
… is a technique which uses a tissue equivalent gas to simulate microscopic tissue sites of the order of cellular dimensions and the principles of gas ionization devices to measure deposited energy. The Gas Electron Multiplier (GEM) has been used since 1997 for tracking particles and for the …

Test and characterization of a new triple-GEM detector
… and characterization of several triple-GEM (Gas-Electron Multiplier) prototype detectors. GEM detectors represent one of the latest developments in a new style of gaseous particle detectors. They have become well-known and widely used. Improvements in foil production are important for future …

Gas electron multipliers and a scanner for automated quality control
The gas electron multiplier (GEM) is a novel charge amplification element for use in gaseous particle detectors. Because of their high gain ([approx.] 10⁵ when cascaded) and ability to withstand harsh radiation conditions, GEMs have been selected for use in the time projection chambers of the …

The readout system of the HERA-B Inner Tracker and prospects of HERA-B in the field of Drell-Yan physics
… the Inner Tracker, which is built of Micro-Strip Gas Chambers with Gas Electron Multiplier (GEM-MSGC) with about 120,000 readout channels. Using results of test beam experiments, the readout system of the Inner Tracker was finalised in its design. At HERA-B, it was extended from small test …

A High Precision Measurement of the Proton Charge Radius at JLab
<p>The elastic electron-proton ($e-p$) scattering and the spectroscopy of hydrogen atoms are the two traditional methods to determine the proton charge radius ($r_{p}$). In 2010, a new method using the muonic hydrogen ($\mu$H)\footnote{A muonic hydrogen has its orbiting electron replaced by a …

Triple-GEM tracker and HCAL-J: two detectors for the study of Nucleon Form Factors at Jefferson Lab.
… focused on two key detectors of SBS: the GEM (Gas Electron Multiplier) based Front Tracker and the HCAL-J segmented hadron calorimeter. The latter is devoted mainly to provide the main trigger in the hadron arm, as well as the particles energy, the neutral pion identification and a course …

Optimization of a GEM-based detector to measure tritium and discriminate against other radiation types
… radiation, with their ability to multiply electrons via avalanches and amplify the signal thereby increasing the ease of detection. This work aims to optimize the design of the collection plate of a GEM-based tritium monitor in order to discriminate between short and long-range beta …
