SPIRAL 2 Budget in M€as stated in the financial agreement signed on Sept. 4th
2006
(manpower)
(additional cost)
Detectors are not included in the investment budget of SPIRAL 2 but France (CEA,CNRS, Region BN) contributes to all equipments constructed at GANIL typically at the level of 30 to 50%.
(Total cost)

SPIRAL 2 on the ESFRI list
Brussels, 19 October 2006
European Research Infrastructures – 35 projects identified
•The ESFRI roadmap (see IP/06/1431) identifies 35 large-scale infrastructure projects at various stages of development. This Memo gives brief details of the projects concerned. The full text of the roadmap, which contains longer descriptions of the projects can be found at: http://cordis.europa.eu/esfri/home.html
• …Isotope beams with SPIRAL 2The project aims at delivering rare (radioactive) isotope beams with intensities not yet available with present machines. SPIRAL 2 will reinforce European leadership in the field of nuclear physics based on exotic nuclei.
