Blumino: The First Fully Integrated Analog SiPM With On-Chip Time Conversion

Edoardo Charbon, Andrei Ardelean, Andrada Alexandra Muntean, Esteban Venialgo Araujo, Emanuele Ripiccini

Blumino is the first analog silicon photomultiplier with integrated amplifier, comparator and time-to-digital converter (TDC). The combination of a photodetector together with on-chip readout circuitry enables system-level advantages, such as internal para ...

Light Extraction Enhancement Techniques for Inorganic Scintillators

Claudio Bruschini, Edoardo Charbon, Francesco Gramuglia, Simone Frasca, Esteban Venialgo Araujo, Emanuele Ripiccini

Scintillators play a key role in the detection chain of several applications which rely on the use of ionizing radiation, and it is often mandatory to extract and detect the generated scintillation light as efficiently as possible. Typical inorganic scinti ...

Plug-and-play TOF-PET Module Readout Based on TDC-on-FPGA and Gigabit Optical Fiber Network

Edoardo Charbon, Esteban Venialgo Araujo

Positron Emission Tomography (PET) scanner technology requires the use of a large number of PET detector modules that work in a parallel and synchronous manner. Moreover, system modularity is a desirable feature, that enables technology reutilization for d ...

Toward a Full-Flexible and Fast-Prototyping TOF-PET Block Detector Based on TDC-on-FPGA

Edoardo Charbon, Esteban Venialgo Araujo

Typically, a time-of-flight (TOF) positron emission tomography (PET) block detector is built using application-specific integrated circuits (ASICs), since they integrate a high number of channels at a reasonable power consumption and into a small area. How ...

An order-statistics-inspired, fully-digital readout approach for analog SiPM arrays

Edoardo Charbon, Esteban Venialgo Araujo

In this paper we present a silicon photomultiplier (SiPM) readout system based on a field-programmable gate array (FPGA), which is capable of converting any commercial 16-channel analog SiPM array into a hybrid device with fully-digital readout for applica ...

Small-animal and endoscopic PET detector modules based on multichannel digital silicon photomultipliers

Edoardo Charbon, Esteban Venialgo Araujo, Augusto Carimatto

In time-of-flight (TOF) positron emission tomography (PET), the coincidence resolving time (CRT) has a strong influence on the overall performance. Multichannel digital silicon photomultipliers (MD-SiPMs) are able to obtain several timestamps for gamma pho ...
