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 کاملImaging with the gas electron multiplier
The Gas Electron Multiplier (GEM), introduced several years ago, is finding numerous applications thanks to its excellent performances in detecting and localizing ionizing radiation. This note summarizes recent developments of the technology, and presents some examples of applications. r 2007 Elsevier B.V. All rights reserved. PACS: 29.40.Cs; 29.40.Gx
متن کاملToward Application of a Thick Gas Electron Multiplier (THGEM) Readout for a Dark Matter Detector
The Yale-Weizmann collaboration aims to develop a lowradioactivity (low-background) cryogenic noble liquid detector for Dark-Matter (DM) search in measurements to be performed deep underground as for example carried out by the XENON collaboration. A major issue is the background induced by natural radioactivity of present-detector components including the Photo Multiplier Tubes (PMT) made from ...
متن کاملSingle photoelectron detection with a low-pressure gas electron multiplier coupled to a CsI photocathode
We have operated the Gas Electron Multiplier (GEM) coupled to a CsI photocathode for the detection of single UV photons. Gains of up to 10 000 were observed with a single GEM in pure hydrocarbons in the range 40}400 Torr. Using a double-GEM structure, we have detected single photoelectrons on a strip electrode. We have studied the single-electron detection e$ciency of the GEM, a crucial paramet...
متن کاملElectron-time Of-flight Spectrometer
A velocity selector is described which is designed for measurement of the total collision cross section of electrons in the energy region below one volt. The system determines the distributions of times of flight of single electrons over a measured path at selected pressures of a specimen gas. The electrons are generated by repetitive illumination of a photo-emitter by a spark gap, pass over a ...
