Oral

Development of high-precision electromagnetic calorimeter prototype featuring the record timing resolution is presented in the report. Significant improvement of timing resolution, compared with electromagnetic calorimeters of the current high-energy experiment, is essential for particle identification. The prototype, based on the ALICE PHOS calorimeter design, is build of PbWO$_4$...

This presentation proposes a novel design of stereo crystal ECal, with the goal of creating a truly homogeneous calorimeter with 2D readout on the outer side of the long crystal bar, and obtaining the third position dimension information by allowing the adjacent layers to have opposite pointing angles with respect to the radius of the cylinder of the detector system, similar to human...

49. Study of the time and energy resolution of an ultracompact sampling calorimeter (RADiCAL) module at EM shower maximum over the energy range 25 ≤ E ≤ 150 GeV using scintillation and wavelength shifting technology.

The RADiCAL Collaboration is conducting R&D on precision-timing electromagnetic (EM) calorimetry to address the challenges expected in future collider experiments under conditions of high luminosity and/or high irradiation such as those expected at the FCC-ee and FCC-hh colliding beam facilities. Under development are sampling calorimeter structures known as RADiCAL modules, based on...

Oral

The Circular Electron Positron Collider (CEPC) is a next-generation electron–positron collider proposed for precision measurement of the properties of the Higgs boson. A major challenge for the CEPC detector is achieving a boson mass resolution (BMR) of 4%, which is required to separate the Higgs, Z, and W bosons in their hadronic decays. The baseline design of the CEPC detector was guided by...

32. Study on the Dynamic Range of SiPMs with Large Pixel Number

Oral

The future Circular Electron-Positron Collider (CEPC) is a large-scale experimental facility, which aims to accurately measure the Higgs boson, electroweak physics and the top quark. For the detector system in CEPC, a highly granular crystal electromagnetic calorimeter is proposed to achieve an EM energy resolution of less than 3%. It is a homogenous structure with long crystal scintillator...
