This paper describes the development of a large area monolithic array type MPPC and its package. The 16 channel 3×3mm elements are fabricated onto one die. A new buttable and non-magnetic type package was also developed for the monolithic array. Finally we describe the time resolution improvements by increasing the quenching resistor parallel capacitance.
A method extending the functionality of silicon photomultipliers (SiPMs) has been developed. It enables the use of SiPMs for quantifying high radiation fluxes in current mode as well as in pulse mode measurements for counting and characterizing individual gamma-ray or X-ray photons when coupled to scintillators. This opens new possibilities for multimodal medical imaging by providing the means for...
Time of flight (TOF) measurements in positron emission tomography (PET) are very challenging in terms of timing performance, and should achieve ideally less than 100 ps FWHM precision. We present a time-based differential technique to read out SiPMs that has less than 25 ps rms electronic jitter. The novel readout is a fast front end circuit (NINO) based on a first stage differential current mode...
