The silicon photo-multiplier physics and technology: a review

• Gianmaria Collazuol (Dipartimento di Fisica e Astronomia, Universita' di Padova, Italy)

Room: Amphithéâtre Pierre Lehmann The physics of the device, the main technological issues and the related solutions adopted by the various manufacturers together with the most recent advances and open issues will be discussed. The device working principles will be covered in detail, by focusing on the phenomena related to avalanches development and to carrier generation and transport in silicon, which are relevant to explain the device intrinsic characteristics like gain, dark noise, after-pulsing, cross-talk, photo-detection efficiency and timing properties. The most relevant characterization measurements related to various types of SiPM devices will be summarized, by focusing on the understanding of the device properties under the influence of various environmental factors (eg. low temperature performances, radiation hardness, light intensity regime etc...) Relationships (in terms of the underlying physics) among the above mentioned intrinsic characteristics will be shown and the resultant tradeoffs (eg timing vs detection efficiency) in actual devices will be discussed. The impact on front-end electronics and on selected application performances will be briefly covered. Finally, possible improvements and future trends will be illustrated and eventually suggested.

Overview of SiPM applications

• Gabriela Llosa (IFIC-Valencia)

Room: Amphithéâtre Pierre Lehmann Multicell Geiger-mode avalanche photodiodes or silicon photomultipliers (SiPMs) have proven to be a sound alternative to other types of photodetectors in different fields, and their advantages can significantly overcome the performance previously achieved or enable new possibilities. Their development continues with the improvement of general properties, and/or the enhancement of determined characteristics to fulfil specific requirements for different applications. As the number of SiPM manufacturers rises, their properties improve, and more possibilities for readout appear in the market, an always increasing number of physics experiments tend to replace other type of photodetectors by SiPMs, or to employ them in innovative applications. SiPMs have been successfully applied, or are being tested, in numerous applications in high energy physics (in calorimeters for CALICE, in T2K or in Cherenkov detectors), in astroparticle physics (such as MAGIC or EUSO), and in medical imaging, for example in the combination of PET and MR imaging modalities, or for time of flight PET. An overview of these and other applications will be given.

Overview of SiPM readout electronics

• christophe de La Taille (CNRS LAL Orsay)

Room: Amphithéâtre Pierre Lehmann Solid-state photomultipliers (SiPM/MPPC) are increasingly popular and replacing vacuum-based devices in many applications. Although their signal properties (gain, capacitance...) are similar and can thus be readout with the same electronics, several dedicated ASICs have been developed worldwide to take benefit of the high level integration that can be reached with these devices. Furthermore, charge and timing measurements can reach unprecedented accuracy and enable new applications in various domains of physics or medical imaging. The talk will review the basic front-end architectures that can be used to take full benefit from the device (voltage/current/charge sensitive preamplifiers, current conveyors...) to optimize their performance. It will also compare the various readout architectures that are being used for readout (discrete, ASICs, waveform digitizers, "digital SiPM" ...). Finally, it will review the status and performance of the various ASICs developed worldwide (SPIROC, BASIC, NINO, PETA, KLAUS, SPIDER, EASIROC, RAPSODI...)
