Tunka-Grande and TAIGA-Muon are scintillation detector arrays that are part of the TAIGA gamma observatory located near Lake Baikal. TAIGA is a hybrid complex of different systems located on an area of 1 km2 and detecting simultaneously secondary charged particles and Cherenkov light produced by extensive air showers (EAS). The experimental scientific program covers gamma-ray astronomy, cosmic...
The KEDR detector at the VEPP-4M accelerator complex plans to measure the mass
of the Y(1S) meson with an accuracy better than 50 keV. This experiment
requires precision measurement of the beam energy. The most accurate method of
measuring beam energy is the resonance depolarization method. The method is
based on the connection of the particle energy with the spin precession
frequency,...
The T2K experiment is a long baseline neutrino oscillation experiment aiming to discover CP violation in neutrino mixing. A new detector, SuperFGD, has been installed in the near detector since October 2023 to reduce systematic errors in the neutrino oscillation analysis. It consists of about 2 million 1 cm scintillator cubes, about 56,000 wavelength shifting fibers penetrating them from three...
The Low Gain Avalanche Diode (LGAD) is a novel silicon sensor known for its excellent timing resolution. The AC-Coupled LGAD (AC-LGAD) is a new type 4D detector developed based on LGAD technology, capable of accurately measuring the time and position information of particles. This presentation will showcase the development status of LGAD and AC-LGAD sensors designed by the Institute of High...
The China Spallation Neutron Source (CSNS) was completed in March 2018, and it is the first spallation neutron source in China. The CSNS project plans to construct four beamlines for beam expansion applications, including a back-streaming white neutron beamline, a medium-energy proton beamline, a high-energy proton beamline, and a surface muon beamline. Around these four beamlines, we have...
Now there are several colliding beam experiments proposed for realisation in a future all around the world. Among them are hadron colliding beam experiment SPD at NICA (JINR, Dubna, Russia)[1], electron-positron colliding beam experiments SCTF (Sarov, Russia)[2], STCF (Hefei, China), CEPC (China)[3], and electron-ion colliding experiment EicC (Huizhou, Guangdong, China) [4]. The construction...
The MIP Timing Detector (MTD) is a new sub-detector planned for the Compact Muon Solenoid (CMS) experiment at CERN, aimed at maintaining the excellent particle identification and reconstruction efficiency of the CMS detector during the High-Luminosity LHC (HL-LHC) era. The MTD will provide new and unique capabilities to CMS by measuring the time-of-arrival of minimum ionizing particles with a...
The ALICE (A Large Ion Collider Experiment) collaboration is gearing up for an upgrade of the Inner Tracking System (ITS2) during the LHC Long Shutdown 3 (2026 - 2028). The upgrade will replace the three innermost layers of ITS2 with a truly cylindrical vertex detector, ITS3. This innovative tracker is composed of a 65 nm CMOS Monolithic Active Pixel Sensor (MAPS) employing stitching...
We have achieved a groundbreaking demonstration of utilizing FNDs as scintillators for imaging synchrotron-based EUV radiation. The carbon-based scintillator comprises an ensemble of NV0 centers serving as the primary source of light emission upon above-bandgap excitation (energy > 5.47 eV or wavelength < 227 nm) within the diamond matrix. These centers exhibit exceptional characteristics,...
Electron-Ion Collider (EIC) is a new collider to explore the fundamental structure and dynamics of matter in the visible world. The EIC project includes a general-purpose detector: The ePIC Detector. The unique physics goals at the Electron-Ion Collider lead to specific design considerations for the electromagnetic calorimeter in the barrel region. The Barrel Imaging Calorimeter comprises...
ALICE 3 is the next-generation heavy-ion experiment proposed for the LHC Run 5 and 6. Its tracking system will be based on a vertex detector, integrated into a retractable structure inside the beam pipe to achieve the best possible pointing resolution, and a large outer tracker, surrounding the vertex detector and covering about eight units of pseudorapidity ($|\eta|<4$). The tracking system...
The Electron-Ion collider (EIC) is designed to collide spin-polarized beams of electrons and ions to study with precision the dynamics of gluons and sea quarks and their role in the structure of visible matter. The ePIC is a general-purpose large-acceptance detector and will be the first experiment operated at the EIC. For studies aiming at the three-dimensional structure of nucleons and...
Liquid argon detectors are used in a variety of fundamental physical experiments, such as dark matter searches and neutrino studies. The use of argon as a target medium is largely due to its high light yield. However, the maximum emission intensity occurs at a wavelength of 128 nm, which is difficult to detect with high efficiency. The standard solution is to use wavelength shifter, which...
Korea CMS is one of the only two organizations, along with CERN micro pattern technology workshop, capable of producing large GEM foils, playing a crucial role in the CMS GEM upgrade. To achieve this, it has built the world's first large GEM production facility using the double-mask etching technology, which is suitable for faster production. The validation results and mass production progress...
The sensitivity of the direct dark matter search is being improved by various energy-sensitive experiments such as XENONnT, LZ, Panda-X and so on. On the other hand, in order to reveal properties of the dark matter particle after its discovery or to explore beyond the neutrino-fog region, direction-sensitive dark matter search is designed and taken place recently.The 3D tracking technology of...
The GEM neutron detector incorporates a layer of boron for neutron capture.
The aim is to offer more cost-effective and larger-scale coverage for neutron detection compared to conventional cold neutron detectors.
We present the results of the beam test using cold neutrons (10 meV) at HANARO (High-Flux Advanced Neutron Application Reactor), analyzing the hit positions of the neutron beam and...
The time performance of photodetector is a critical parameter for the development of Radiation Imaging Detectors based on time of flight (TOF) technique, for example TOF positron emission tomography (TOF-PET). In 2020, the proposal of roadmap toward the 10 ps TOF-PET challenge places higher requirement on the time performance of the photodetector. Microchannel Plate Photomultiplier (MCP-PMT)...
