Abstract
Abstract
Medical applications, such as Positron Emission Tomography
(PET), and space applications, such as Light Detection and Ranging
(LIDAR), are in need of 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 with Radioroc 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 photomultiplier (SiPM) technologies available on the
market, coupled to different scintillation crystals. The best
single-photon time resolution (SPTR) was achieved using FBK NUV-HD
SiPMs with an FWHM of 90 ps with Liroc and 73 ps with
Radioroc. Furthermore, the coincidence time resolution (CTR) of
Radioroc was studied with different crystal sizes. Using a large
LYSO:Ce,Ca crystal of (3 × 3 × 20 mm3) with Broadcom
Near UltraViolet-Metal in Trench (NUV-MT) yields a CTR of 127 ps
(FWHM). The best CTR of Radioroc was determined to 83 ps (FWHM)
with Broadcom NUV-MT SiPMs coupled to LYSO:Ce,Ca
(2 × 2 × 3 mm3)) from Taiwan Applied Crystal (TAC).
