Renewed efforts The first LAL-IHEP agreement was signed in 1988 by Michel Davier and Minghan Ye for the collaboration in particle and accelerator physics.

Happy collaborations on food Francoise ， seen happily in these pictures, is very Knowledgeable in Chinese art history and started to speak Chinese since this trip

Michel’s Contribution to BES I/II Advised on Physics program – Tau mass scan at BES I – R measurement at BES II

Many reviews & workshops Beijing Tau-Charm Factory(BTCF) workshop, Feb Review committee chair on BTCF, Nov Review committee chair on BESIII detector, Apr Review committee chair on BESIII detector, Sep Nov. 1996Feb. 1996

Apr. 2001Apr. 2001, with Ming-Han Ye, 13 years after they signed the agreement Apr Sep. 2002

The BESIII Detector Be beam pipe SC magnet, 1T Magnet yoke MDC, 120  m CsI(Tl) calorimeter, 2.5 TOF, 90ps RPC Question: Longer CsI(Tl) crystals or SC magnet ? Michel’s recommendation: Both Money ？ Not a problem

不识庐山真面目，只缘身在此山中 宋 苏轼 ( ) you don’t recognize the real shape of the mountain Lu just because you are in the middle of it Su Shi ( ) Michel was right. It appears that he understands well Chinese politics, certainly better than I do Mountain Lu, Jiangxi Province, China,. Photo by YFW

Sino-French collaboration on particle physics is now in a great shape, thanks to all pioneers

Thanks, Michel, we will all remember what you did Congratulations, Michel
