Hyper-Kamiokande is an international collaboration as a leading worldwide experiment to address fundamental unresolved questions in particle physics and cosmology. The project includes the construction of Hyper-Kamiokande detector, J-PARC beam upgrade, and the near detector upgrade/construction. Many physics opportunities are available; CP violation and neutrino mass ordering, a search for...
The Jiangmen Underground Neutrino Observatory(JUNO) is a next-generation neutrino experiment located 700m underground in Southern China. The detector will use a 20 kton liquid scintillator equipped with 17612 20-inch PMTs and 25600 3-inch PMTs, with the photocathode coverage reaching ~78%. The detector is designed to reach a high energy resolution of 3% at 1 MeV for neutrino mass ordering(MO)...
A new technique for ion identification in Accelerator Mass Spectrometry (AMS) has been proposed by measuring the ion track ranges using a low-pressure TPC. As a proof of principle, a low-pressure TPC with charge readout using a THGEM multiplier was developed. The tracks of alpha particles from various radioactive sources were successfully recorded in the TPC. The track ranges were measured...
Search for neutrinoless double beta decay (0νββ) is a key experiment to answer unresolved properties of neutrino. Experimental observation of 0νββ will provide a direct answer to the particle type of neutrino (i.e., the Dirac-or-Majorana question), validate lepton number violation in the field of particle physics, and confine the absolute mass scale of neutrino. A number of large scale...
The GEM detector is useful for various fields, not only high energy physics. But, one uncomfortable feature is to be broken due to a large discharge. One large charge deposit makes a trigger to lead the large discharge and to carbonize inside the GEM hole. In order to avoid such a bad situation, we are developing new GEM foil without carbon. One good solution is to apply ceramic as an...
We proposed a new type of hybrid photo-detector involving photocathode, scintillator, and silicon photomultiplier (SiPM) in vacuum enclosure. Photons incident onto the photocathode are converted to photo-electrons. Then the photo-electrons are accelerated toward the scintillator by the electric field between the photocathode and electrode to produce scintillation lights. The scintillation...
Taiwan Instrumentation Detector Consortium (TIDC) has been officially initiated recently. The main goal is to establish common infrastructures and resources among the Taiwan HEP community. The TIDC, formally known as Taiwan Silicon Detector Facility (TSiDF), currently serves as an important silicon module assembly center for LHC & BNL upgrade projects. The research team of TIDC consists of...
SOI is a CMOS LIS technology where the MOSFETs are produced on the SiO$_2$ layer (BOX) above silicon wafers. SOI pixel sensor utilize the silicon wafer as the radiation sensor and the signal induced in the wafer is processed by the CMOS circuit on BOX. The parasitic capacitance of the circuit is smaller than that in the normal bulk CMOS, the power consumption can be suppressed than the...
The Circular Electron Positron Collider (CEPC) has been proposed as a Higgs Factory and aimed for high precision measurement of the Higgs boson. Collisions at lower center-of-mass energies will also allow precision measurement of electroweak observables. To fulfill the stringent requirement of precision tracking of charged particles, the tracking system must be constructed with the...
To meet the high precision physical goals in the future e$^+$e$^−$ circular collider (CEPC), the high resolution tracker detector for the particle track reconstruction ($\lt$100$\mu$m) and particle identification are demanded. Time Projection Chamber (TPC) is one of the main concept option of the central tracker detector. the status and update R&D results of TPC module and prototype for the...
The last few years has seen the largest underground dark matter searches rapidly approach their purported ultimate sensitivity limit, the so-called "neutrino floor". An experiment reaches the neutrino floor went it becomes so large and so sensitive that the background from coherent nuclear scattering of astrophysical neutrinos starts to drown out a potential dark matter signal. The...
The detector developments for fast and super-fast time-resolved studies at SR beams will be reviewed. Two detectors based on Si micro-strip technology are developed at present in Budker INP SB RAS. The detector for imaging of super-fast processes at a nanosecond scale, DIMEX-Si allows to improve by more than a factor of ten maximum detected photon flux, with respect to the gaseous version of...
The electron-positron collider VEPP-2000 is operating now at Budker Institute of Nuclear Physics. Two detectors CMD-3 and SND are installed in the interaction
regions of the collider. From 2010 until now the total collected luminosity integral is about 2 X 300 pb−1. CMD-3 is a general purpose detector designed to study e+e− annihilation into hadrons in the whole energy range of the collider -...
Taiwan Applied Crystal Co., LTD develops a series process to produce high light yield and fast timing scintillator. Patented recipes from NSYSU and
unique crystal growth to meet those requirements.
The Compact Muon Solenoid (CMS) detector at the European Council for Nuclear Research (CERN) Large Hadron Collider (LHC) is undergoing an extensive Phase II upgrade program to prepare for the challenging conditions of the high-luminosity LHC (HL-LHC). In particular, a new timing layer will measure minimum ionizing particles (MIPs) with a time resolution of ∼30–40 ps and hermetic coverage up to...
The dual-readout method is a state of the art calorimetry technique enables high-quality energy measurement for both electromagnetic and hadronic particles, which has been developed during last two decades. The dual-readout calorimeter detector mainly designed by Korean team has been included in the conceptual design reports of both FCC-ee and CEPC projects published in 2018. As a next step,...
