1. Introduction by Joao

1) Submit Letter of Intent for Snowmass 2021

For every sub-group, please provide 2 pages document for describing your project, challenge and questions to be answered, and your research and contact. The responsible person for each group are as follow:

• TPC: Huirong will provide document
• Crystal Calorimeter: Yong agreed to provide document.
• Solenoid Magnet: Feipeng will provide document
• PFA Calorimeters: Jianbei will provide the document
• Drift Chamber: Franco Grancagnolo and Roberto
• Dual Readout Calorimeter: Franco Grancagnolo and Roberto. If one has more than one concept, it;s OK to provide LOI respectively. 
• MuRwell: Xiaolong agreed to help
• Tracker Silicon: Meng agreed to provide the document in last meeting.
• Vertex: Need offline discussion to decide who can help.
• MDI: Hongbo

Please submit a version in a week. We need to show an integrated version on next CEPC Steering Committee meeting (June 15th)

2. Huirong reported the update on TPC R&D

Huirong introduced some update progress of the TPC prototype R&D in last three months; update progress of the TPC ASIC chips R&D and testing for power consumption and noise. Also they are carrying up the collaboration of the new concept R&D with Nikehf.

Jianbei suggested to mentioned double Meshes concept is coming from double meshes detector developed by USTC group.

3. Feipeng reported CEPC HTS plan and Radiation thickness calculation

Feipeng introduced HTS concept, calculated radiation thickness and compared the results with LTS concept. Next step, they will more focus on developing HTS cables.
