DESCRIPTION:Speakers: Ping Chen （陈萍） (Xi’an Institute of Optics 
 and Precision Mechanics (XIOPM)\, Chinese Academy of Sciences (CAS))\n\nAb
 stract :Photomultiplier tubes (PMTs) remain among the most sensitive detec
 tors for ultraviolet\, visible\, and near-infrared light\, enabling single
 -photon detection through an efficient electron multiplication process. Th
 ey are widely used in high-energy particle detection\, nuclear physics exp
 eriments\, and high-energy astronomy. This overview begins by examining th
 e fundamental operating principles of PMTs—specifically photoelectron em
 ission\, electron-optical focusing\, and secondary emission gain—and hig
 hlights their key performance metrics. PMTs are characterized by dozens of
  performance parameters\, which often involve trade-offs\; therefore\, app
 lication-specific design is essential to meet varying experimental require
 ments. The overview then addresses how each parameter can be tailored and 
 optimized for practical needs. It also traces the technological evolution 
 from traditional glass-envelope PMTs to advanced configurations\, includin
 g position-sensitive\, mesh-dynode\, and microchannel plate (MCP) PMTs\, a
 s well as hybrid devices that integrate semiconductor-assisted readout. De
 spite competition from solid-state detectors\, PMTs offer distinct advanta
 ges\, including low-noise amplification\, large effective area\, and radia
 tion tolerance.Biography:Ping Chen is a professor at the Xi’an Institut
 e of Optics and Precision Mechanics (XIOPM)\, Chinese Academy of Sciences 
 (CAS)\, where she earned her Ph.D. in early 2017 after beginning her studi
 es there in 2011. Her doctoral research focused on the study of large-area
  photomultiplier tubes (PMTs)\, marking the start of her work in this fiel
 d. She conducted joint doctoral research at Université Paris-Sud (Paris X
 I) from 2015 to 2016\, and subsequently served as an assistant researcher 
 (2017–2019) and associate researcher (2020–2023) at XIOPM. During this
  period\, she also completed an in-service postdoctoral fellowship at Shan
 ghai Jiao Tong University (2017–2022). She has been a full researcher si
 nce 2024\, and in 2026 she was appointed Deputy Director of the State Key 
 Laboratory's Center for Ultrafast Detection and Imaging. Her contributions
  include the simulation design of 20-inch PMTs for the Jiangmen Undergroun
 d Neutrino Experiment (JUNO)\, the development and mass production of gate
 d microchannel plate (MCP) PMTs for the Double Cone Ignition (DCI) experim
 ent\, and the development of long-lifetime position-sensitive MCP-PMTs for
  the Super Tau-Charm Facility (STCF). She is also a member of the CERN DRD
 4 Collaboration Committee for photon detection and particle identification
