Vertex Detector Meeting Minutes

Date: 2024/2/1
Time: 14:30 – 16:00
Participants: Zhijun Liang, Mingyi Dong, Wei Wei, Ying Zhang, Jun Hu, Hongyu Zhang, Ouyang Qun, Yang Zhou, Jinyu Fu, Tianya Wu, Manqi Ruan, Miao He
Minutes: Zhijun Liang

• Report on the R&D status of sub-detectors

  • Zhijun: Introduction to the CEPC reference TDR project and updates on the TDR key parameters from the accelerator TDR related to the Vertex detector

• Discussions:

  • Mingyi: Meng Wang assigned Mingyi to be the acting L3 contact for Stitching technology
  • Mingyi: Stitching does not contradict with SOI or CMOS pixel. Propose to mention Stitching technology as one option in the reference TDR, but it is not competing for the baseline design for this TDR study
  • Weiwei: Propose to add Ying Zhang as the frontend electronics L3 contact in this TDR project
  • Zhijun: In TDR, we should mention the key parameters for now and in the next 5 years when the CEPC detector is going to be built. Cooling design will be based on the expected Power dissipation in 5 years. 
  • Discuss the key parameters for justifying the choice of technology:
    • Single-point spatial resolution (now and in the next 5 years)
    • Time stamp precision requirement (to be discussed with Shengsun Sun from the reconstruction group)
    • Material budget
    • Cost estimation
    • Max data rate that can be handled by this technology (now, and in the next 5 years)
    • Radiation hardness (now, and in the next 5 years)
    • Power dissipation (now, and in the next 5 years)
    • Expected Technology availability in the future
    • Technology Readiness

• Discuss about including more people from Universities, will do from next meeting. 

• Discussion about the timeline (draft):

  • By early March: finalizing the selection of technology
  • By early April: first version of vertex layout geometry

 

Discussion with Yunpeng @ Feb 5th 

Minutes: Zhijun Liang

• Yunpeng propose to focus on CMOS pixel technology, He propose to work on L3 CMOS related topic.

• Agree on focusing on CMOS pixel technology as baseline for reference TDR
