FCPPL-ALICE project (2011) • funding from France. Total: 42 200 Euros • travel costs for French Physicists to the FCPPL workshop • travel costs for the Ph. D defense of Yaxian & Renzhuo • stay costs for 2 Chinese Ph. D students in France (Yaxian & Xiaoming) • stay costs for 2 Chinese master-II students in France • stay costs for 2 Chinese technicians in France • funding from China. Total: 341 000 Yuan • travel costs for Chinese physicists, technicians & students in France • stay costs for French physicists in Jinan & Wuhan • stay costs for Chinese physicists in France • concern: the reduction of the French budget (14 000 Euros attributed for a request of 42 200 Euros) strongly affects the future collaboration only 2 French people in Jinan, stay of Chinese people in France to be redefined or cancelled. (20 000 Euros in 2010…) 1 Euro = 9. 3 Yuan Philippe. Crochet@clermont. in 2 p 3. fr FCPPL workshop, Jinan, 07/04/2011 19

Summary The FCPPL-ALICE Chinese/French collaboration is solid, healthy and very fruitful • excellent contributions of students • large scientific production • technical contribution to DCAL is ongoing The French budget cut will limit the collaboration actions inside the FCPPL Philippe.
