Start to End Error Study for the Spiral2 Linac

The possibility of a high intensity accelerator at GANIL, producing secondary beams of unprecedented intensity, is considered. The proposed CW driver for the SPIRAL2 project aims to accelerate a 5 mA deuteron beam up to 20 A. MeV and a 1 mA ion beam for q/A = 1/3 up to 14.5 A. MeV [1]. The error sensitivity study which has been performed for this linac in order to define the tolerances for the construction is presented. The correction scheme and the expected losses are described. The Extreme Value Theory is used to estimate the expected beam losses.
