THE SILICON PHOTOMULTIPLIER:AN IN-DEPTH ANALYSIS IN THE CONTINUOUS WAVE REGIME

2014

The Silicon Photomultiplier (SiPM) is a novel solid state photon counting detector consisting of a parallel array of avalanche photodiodes biased beyond their breakdown voltage. It has known a fast development in the last few years as a possible alternative to vacuum photomultiplier tubes (PMTs) and conventional avalanche photodiodes (APDs). Indeed, current research in photodetectors is directed toward an increasing miniaturization of the pixel size, thus both improving the spatial resolution and reducing the device dimensions. SiPMs show high photon detection efficiency in the visible and near infrared range, low power consumption, high gain, ruggedness, compact size, excellent single-phot…

How relevant is Kotter’s change theory on organizational change in meta-organizations : A case study of the ESNreview of the Erasmus Student Network

2019

Master's thesis Public Policy and Management ME502 - University of Agder 2019 Kotter’s 8-step organizational change model is amongst the most popular change models in the world, however despite its continued success as a popular science approach to the topic of organizational change, it has received limited attention from the scientific community, and little research has been done into how the model works in practice. This thesis is a case study into the use of Kotter’s change model, researching how well it may fit into a meta-organization. According to Ahrne and Brunsson, a lot of organizations may be described as meta-organizations, yet the research into this unique structure and its effe…

Signal to noise ratio measurements of silicon photomultipliers in the continuous wave regime

2014

We report on our signal to noise ratio (SNR) measurements carried out, in the continuous wave regime, on a novel class of silicon photomultipliers (SiPMs) fabricated in planar technology on silicon p-type substrate.

Signal to noise ratio measurements of silicon photomultipliers

2014

We report on our signal to noise ratio (SNR) measurements carried out, in the continuous wave regime, on a novel class of silicon photomultipliers (SiPMs) fabricated in planar technology on silicon p-type substrate. SiPMs are large area detectors consisting of a parallel array of Geiger Mode APDs with individual integrated quenching resistors. Each photodiode is an independent photon counting microcell and is connected to a common analog output to produce a summation signal proportional to the number of detected photons [1], [2]. SNR of SiPMs is expressed by the ratio of the SiPM average signal current and the RMS deviation of the overall current (i.e., the overall shot noise current). The …
