The Absolute Detection Efficiency of a Channelplate 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...

assessment of the efficiency of s.p.g.c refineries using network dea

data envelopment analysis (dea) is a powerful tool for measuring relative efficiency of organizational units referred to as decision making units (dmus). in most cases dmus have network structures with internal linking activities. traditional dea models, however, consider dmus as black boxes with no regard to their linking activities and therefore do not provide decision makers with the reasons...

The detection efficiency of electron multipliers

The variation of the detection efficiency of electron multipliers used in the pulse-counting mode is investigated as a function of the average gain per dynode, the energy of the electrons being detected and the applied voltage. It is assumed that the pulse-height distributions can be obtained from Polya statistics and that the universal yield curve for secondary emission is applicable. Results ...

Absolute Photo Detection Efficiency measurement of Silicon PhotoMultipliers

Silicon photomultipliers (SiPM) are recent detectors studied by many groups. Their proprieties (compact form, insensitivity to magnetic fields, low voltage power supplies...) are promising for various scientific fields, from high energy physics calorimetry to medical imaging application. An accurate measurement of the SiPM parameters is needed to integrate these devices in experimentation. Abso...
