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...

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

Photo-Electron Multiplier on the Basis of Multilayered Semiconductor Structure

In the paper, a new physical principle for designing of a new optoelectronic device and its theoretical description are presented. The basic idea of the device consists in providing inside a multilayered semiconductor structure such conditions for photoelectrons that enable sequential avalanche multiplication of electrons and holes inside two depletion slabs created around p-n junctions of a re...

Resonating Silicon Beam Force Sensor

A resonating silicon-beam force sensor is being developed using micromachining of silicon and IC-compatible processes. Results are reported here of measurements on the force-to-frequency transfer of bare silicon prototypes. The measurements with forces on the sensor beam up to 0.4 N show a frequency shift of 3.1 to 5.2 times the unloaded resonance frequency f. (fo = 3 to 5 kHz), depending on th...
