70. Recent development of MPPC and Si detectors for HEP experiments

Mr Koei Yamamoto (Hamamatsu Photonics)

Oral

Nearly 10 years have passed since Hamamatsu started developing the MPPC, which is a part of the SiPM family. The most important feature is its photon counting capability due to its high gain and low noise, but the MPPC has many additional features such as compact size, low operation voltage, robustness, high detection efficiency, and immunity to magnetic fields. Over the years, various types...

5. High-Density Silicon Photomultipliers with Epitaxial Quenching Resistors at NDL

Oral

Silicon photomultipliers (SiPMs), also known as multi-pixel photon counters (MPPCs), represent an alternative solution that to a large extent combines the advantages of PMTs and APDs. They have high gain, low bias voltage, excellent timing properties and are insensitive to magnetic fields. SiPMs are replacing the traditional PMTs gradually in various applications like high energy physics,...

28. Development of High-density NIR sensitive Silicon photomultipliers at FBK

Fabio Acerbi (FBK)

Oral

Analog silicon photomultipliers (SiPMs) have obtained growing attention as an alternative to the traditional photomultiplier tubes in detection of scintillation light, e.g., in nuclear medicine and high-energy physics. However, SiPMs are also emerging as very sensitive detectors in many single-photon or few-photons applications, like: LIDAR, optical spectroscopy, Cherenkov radiators and NIR...

25. Direct Measurement of Optical Cross-Talk in SiPMs Using Light Emission Microscopy

Derek Strom (Max Planck Institute for Physics)

27/11/2018, 11:25

Oral

Silicon Photomultipliers (SiPMs) are attractive light detectors for high energy and astroparticle physics experiments. They are compact in size, have fast (few ns) response time, operate at lower voltage compared to classical photomultiplier tubes, are insensitive to magnetic fields, and the newer samples offer photon detection efficiencies of > 40%. The optical cross-talk effect, whereby...

18. Experimental SiPMs parameter characterization from avalanche triggering probabilities

Giacomo Gallina (TRIUMF)

27/11/2018, 11:45

Oral

Silicon photo-multipliers (SiPMs) are detectors sensitive to single photons that are widely used for the detection of scintillation and Cherenkov light in subatomic physics and medical imaging. In order to understand the over-voltage dependence in detail, we have built a new model by extracting the electron and hole avalanche triggering probabilities using VUV and Infra-red light sources. Then...

24. Characterization of SiPM Optical Crosstalk and its Resin Thickness Dependence

Mr Yuki Nakamura (Nagoya University)

27/11/2018, 12:05

Oral

Silicon photomultipliers (SiPMs) are widely used in many applications in medical imaging, particle physics, and high-energy astrophysics owing to their high photon detection efficiency, high charge resolution, compactness, and low voltage. It is known, however, that so-called optical crosstalk (OCT), which generate secondary infrared photons in the micro silicon cell that fired first, can...
