A PET scanner based on silicon photomultipliers (SiPMs) has been widely used as an advanced nuclear medicine imaging technique that yields quantitative images of regional in vivo biology and biochemistry. The compact size the SiPM allows direct one to coupling between scintillation crystal photosensor, yielding better timing energy resolutions than light sharing methods have be photomultiplier ...

This note describes continued studies at Fermilab of the long term stability of a small water Cerenkov tank. The water tank, bag liner, water, photomultiplier tube, and data acquisition software were unchanged for the additional measurements from June to November, 1999. However, some details of the geometry of the trigger counters relative to the tank and of the electronics may have differed. T...

The Silicon Photomultiplier (SiPM) sensor is replacing the extensive use of Tube (PMT) in fast timing applications. These photo-sensors can be applied different fields such as medical imaging systems like Positron Emission Tomography (PET), LIDAR technologies or High Energy Physics (HEP) experiments. More specific, Time-of-Flight PET (ToF-PET) requires further developments to achieve a Coincide...

A minimally perturbing plastic scintillation detector has been developed for the dosimetry of high-energy beams in radiotherapy. The detector system consists of two identical parallel sets of radiation-resistant optical fibre bundles, each connected to independent photomultiplier tubes (PMTs). One fibre bundle is connected to a miniature water equivalent plastic scintillator and so scintillatio...

In recent years it has been shown that PET is capable of obtaining in vivo metabolic images of small animals. These serve as models to study the development and progress of diseases within humans. Imaging small animals requires not only image resolution better than 2 mm, but also high sensitivity in order to image ligands with low specific activity or radiochemical yields. Toward achieving thes...

A microcontroller-based photon counting system has been developed by the Laser and Medicine-Technology gGmbh, Berlin, Germany, in cooperation with the University of Athens. This microcontroller-based system controls, acquires, processes and stores the data from a high-resolution multichannel gas analyzer based on linear vibrational Raman scattering. The system described provides accurate photon...

The Tile Calorimeter (TileCal) is a sampling hadronic calorimeter covering the central region of ATLAS experiment, with steel as absorber and plastic scintillators active medium. High-Luminosity phase LHC, delivering five times LHC’s nominal instantaneous luminosity, expected to begin in 2029. TileCal will require new electronics meet requirements 1 MHz trigger, higher ambient radiation, ensure...

The construction and use of a dual radiator Ring Imaging Čerenkov (RICH) detector is described. This instrument was developed for the HERMES experiment at DESY which emphasises measurements of semi-inclusive deep-inelastic scattering. It provides particle identification for pions, kaons, and protons in the momentum range from 2 to 15 GeV, which is essential to these studies. The instrument uses...

The article presents the data related to the flame acquisitions in a liquid-fuel gas turbine derived burner operating in non-premixed mode under three different equivalence fuel/air ratio, which corresponds to a richer, an intermediate, and an ultra-lean condition, near lean blowout (LBO). The data were collected with two high speed visualization systems which acquired in the visible (VIS) and ...

A new neutron time-of-flight (nTOF) detector for fuel-areal-density measurements in cryogenic DT implosions was installed on the OMEGA Laser System. The nTOF detector has a cylindrical thin-wall, stainless-steel, 8-in.-diam, 4-in.-thick cavity filled with an oxygenated liquid xylene scintillator. Four gated photomultiplier tubes (PMTs) with different gains are used to measure primary DT and D2 ...
