Radiation Detection Using the Parallel Channel Electron Multiplier

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...

The Absolute Detection Efficiency of a Channelplate Electron Multiplier

Photoionisation detection of single 87Rb-atoms using channel electron multipliers

Fast and efficient detection of single atoms is a universal requirement concerning modern experiments in atom physics, quantum optics, and precision spectroscopy. In particular for future quantum information and quantum communication technologies, the efficient readout of qubit states encoded in single atoms or ions is an elementary prerequisite. The rapid development in the field of quantum op...

Imaging 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

The Channel Multiplier Cathode-ray Tube

This paper describes a new approach to cathode-ray tube design aimed at achieving a significant depth reduction. The addressing function of the electron beam has been separated from the light generation process by a channel electron multiplier array, allowing the use of a novel deflection system based on a low-power scanning beam. Monochrome versions of the thin tube have been made with a 12" (...
