Project details

Project astract DASIPM2 is a project aimed at the development and application of a very powerful new technology, Silicon photomultipliers (SiPMs), in which there is a rapidly growing interest from many different areas of the physics community. The semiconductor photon detectors in question have properties comparable to those of a traditional photomultiplier tubes PMT but with additional advantages, such as compactness, low operational voltage and insensitivity to magnetic fields. However, this novel technology still needs to be improved in order to be commercially employed as photodetectors. The aim of the DASIPM2 project is both the improvement of the present technology and the development of 1D and 2D arrays of such devices at ITC-irst for their use as photodetectors, and their application to different areas.

DISI Sub-project details

Project astract The first SiPMs have already been produced at ITC-irst, showing improved properties with respect to the ones provided by Russians and previously tested. In particular, the recently developed SiPMs have increased sensitivity in the blue /green region of the spectrum where most scintillators have their peak emission, showing 40-50% photo-detection efficiency (not considering the geometrical efficiency) at 440 nm wavelength, and there is still room for improvement. The project now aims at creating matrices of SiPMs with optimized properties, so that new technological processes will be implemented in order to surmount the challenges of developing the optimized SiPMs and forming them into matrices. An important issue that arises when dealing with matrices is the readout scheme, since traditional methods reduce the active area, and, as a consequence, the geometrical efficiency of the device. The implementation of backplane readout for the SiPM matrices will be one of the main objectives of this project.
