Characterization of CMOS SPADs for future RICH Detectors
R. Dolenec, H. K. Yildirim, G. V. Tran +12
In the planned or considered upgrades of LHCb, ALICE and Belle II experiments, the Ring imaging Cherenkov (RICH) detectors will have to be improved in order to function at increase…
Characterisation of the LAPPD, a large area microchannel-plate PMT
S. Korpar, R. Dolenec, F. Grijalva +7
We present a comprehensive characterization of the LAPPD Gen-II, a large-area microchannel-plate photomultiplier tube (MCP-PMT) equipped with a capacitively coupled sensing (readou…
Below 100 ps CTR using FastIC+, an ASIC including on-chip digitization for ToF-PET and beyond
D. Mazzanti, S. Gomez, J. Mauricio +19

Recent developments in data reconstruction for aerogel RICH at Belle II
Luka Santelj
In the forward end-cap of the Belle II spectrometer, particle identification is provided by a proximity focusing RICH detector with an aerogel radiator (ARICH). The ARICH's primary…
LAPPD operation using ToFPETv2 PETSYS ASIC
A. Seljak, M. Bračko, R. Dolenec +4
Single photon sensitive detectors used in high energy physics are, in some applications, required to cover areas the size of several m2, and more specifically in very strong demand…
Intermodular Configuration Scrubbing of On-detector FPGAs for the ARICH at Belle II
R. Giordano, Y. Lai, S. Korpar +5
On-detector digital electronics in High-Energy Physics experiments is increasingly being implemented by means of SRAM-based FPGA, due to their capabilities of reconfiguration, real…
Performance evaluation of the aerogel RICH counter for the Belle II spectrometer using early beam collision data
M. Yonenaga, I. Adachi, L. Burmistrov +32
The Aerogel Ring Imaging Cherenkov (ARICH) counter serves as a particle identification device in the forward end-cap region of the Belle II spectrometer. It is capable of identifyi…
