Study experimental time resolution limits of recent ASICs at Weeroc with different SiPMs and scintillators

Résumé

Medical applications, such as positron emission tomography (PET), and space application, such as Light Detection and Ranging (LIDAR), are in need for highly specialized ASICs. Weeroc, in collaboration with different partners, is highly involved in developing a new generation of front-end ASICs. In the context of a joined LIDAR project among Weeroc, CNES, and Airbus, Weeroc is working on the development of Liroc, an ASIC for space LIDAR application. Weeroc is also working on advancing ASICs for medical applications, hence, another ASIC, Radioroc, is under development and intended to be used for PET applications. This study experimentally evaluates the time resolution limits of these ASICs in different configurations, with some of the most recent silicon photomultipliers (SiPMs) technologies available on the market coupled with different scintillation crystals. The best single-photon time resolution (SPTR) was achieved using FBK NUV-HD SiPMs with an FWHM of 79 ps with Liroc and 73 ps with Radioroc. Furthermore, the best coincidence time resolution (CTR) of Radioroc was determined to 83 ps (FWHM) with Broadcom Near UltraViolet - Metal Trench (NUV-MT) SiPMs coupled to TAC LYSO:Ce,Ca (2x2x3 mm3).
