Jean-Frédéric Irène CurieJoliot-Curie(1900 - 1958) (1897-1956)

Founding director of the Institute of Modern Physics Established in 1950

IHEP & BEPCOrsay Campus ： LAL & INP

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

Fruitful exchange program: many become key players of the field

• Zhiqing Zhang• Jiawen Zhang• Shaomin Chen• Changzheng Yuan• Wenfeng Wang• Liangliang Wang

• Jie Gao• Nan Huang• Mengping Gu• Yi Sun• Hong Sun

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. 1996• Review committee chair on BTCF, Nov. 1996 • Review committee chair on BESIII detector, Apr. 2001• Review committee chair on BESIII detector, Sep. 2002

Nov. 1996 Feb. 1996

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

Apr. 2001 Sep. 2002

The BESIII Detector

Be beam pipe

SC magnet, 1TMagnet yoke

MDC, 120 m

CsI(Tl) calorimeter, 2.5 %@1 GeV

TOF, 90ps

RPC

Question: Longer CsI(Tl) crystals or SC magnet ?Michel’s recommendation: BothMoney ？Not a problem

不识庐山真面目，只缘身在此山中 宋 苏轼 (1037-1101)you don’t recognize the real shape of the mountain Lu just because you are in the middle of it Su Shi (1037-1101)

Michel was right. It appears that he understands well Chinese politics, certainly better than I do

New era• Creation of the France-China Particle Physics Laboratory

(FCPPL) on April 10, 2007• A joint laboratory « without wall », ~50 collaborating

projects supported• Steering Committee, co-chaired by Michel and Hesheng,

consists of 8+8 members for project selection and evaluation

• Annual workshops:• Jan. 2008 : Marseilles• Mar. 2009 : Wuhan• Apr. 2010 : Lyon • Apr. 2011: Jinan• 2012: Saclay

Steering committee meeting, Apr. 2011: Jinan

2,5 days dedicated to scientific talks on Sino-French projectsFollowed by the annual meeting of the Steering Committee

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
