The high-granularity homogeneous electromagnetic calorimeters (ECALs), designed for future lepton colliders, demonstrate outstanding electromagnetic energy resolution and maintain sufficient low-energy photon detection capability. This demands an excellent electronic system for the readout of silicon photomultipliers (SiPMs), capable of covering a wide dynamic range from single photons to...

Dual-readout calorimeters utilize two distinct readouts from scintillation and Cerenkov fibers to measure energy, yielding high hadronic energy resolution. While these calorimeters can reconstruct the energy, position, and particle type of detected showers, conventional methods are limited to distinguishing between electromagnetic and hadronic particles. To overcome this limitation, we explore...

The HKROC ASIC was originally designed to readout the photomultiplier tubes (PMTs) for the Hyper-Kamiokande (HK) experiment. HKROC is a very innovative ASIC capable of readout a large number of channels satisfying stringent requirements in terms of noise, speed and dynamic range. Each HKROC channel features a low-noise preamplifier and shapers, a 10-bit successive approximation...

This research focuses on the development of next-generation calorimeter technology that opens access to a '5D calorimeter,' which measures not only energy but also the precise hit position and timing. This technology integrates two key techniques: the 'high-granularity calorimeter' and the 'dual-readout calorimeter,' while also incorporating picosecond-level timing resolution. Within this...

Large Hadron Collider (LHC) produces many energetic mesons with energies of several TeV in the very forward region of the collisions. The LHC forward (LHCf) experiment measures $\pi^0$, $\eta$, $K^0_s$ as well as single photons and neutrons with two detectors called as LHCf-Arm1 and Arm2, which were installed 140 m away from the ATLAS interaction point and cover the pseudorapidity region of ฮท...

Quarks and gluons, which are normally confined within hadrons by strong interactions, are released from the confinement at high temperatures and densities, which is called quark-gluon plasma (QGP). To understand QGP, high-energy heavy ion collision experiment has been produced in laboratory and research has been carried out to investigate this property. One of unknowns about the QGP is that it...

The Hadron Calorimeter (HCAL) of the CMS experiment comprises two different technologies. The barrel and endcap regions of the HCAL are composed of layers of brass absorber plates interleaved with plastic scintillator tiles, and the barrel is augmented by an additional layer of scintillators beyond the CMS magnet. These subdetectors are read out by silicon photomultipliers (SiPMs) present on...

Due to its continuously adjustable composition and low cost, glass scintillator (GS) has become a new choice for solid scintillation materials. Compared to scintillation crystals, glass can achieve a similar density (approximately 6 g/cm3) at a lower cost, making it the preferred luminescent device for scintillation detectors. However, research on glass scintillator has mainly focused on...
