On June 15, Dr. Hongming Tang, Director of Magnet Division, led a team to attend the ICFA Mini-workshop on high field magnets for PP colliders held in Shanghai Jiaotong University. During this time, we had an in-depth communication and exchange with many international and domestic experts on gas pedal superconducting magnets. Dr. Wei Wu from Lanzhou Institute of Modern Physics and Dr. Zian Zhu and Qingjin Xu from Beijing Institute of High Energy Physics also visited Centron.
