Popis:	Radioactive Ion Beams of SPIRAL2 project will be produced in the ECR ion source using the Helium as supporting gas. RIB transported in the transfer lines have a multi-component structure and total current of the beams is defined by Helium ions. The total power of Helium component may reach 300 W. The focusing force acting on the ions in the transfer beam line is strongly dependent on mass-to-charge ratio (this is valid for magnetic optical elements). For this reason supporting gas ions will be lost at initial part of the beam line between ECR ion source and analyzing magnet. The Helium beam losses and induced heating power density at the wall of vacuum tube in RIB transfer line of SPIRAL2 during transportation of Ar, Xe and U ion beam are evaluated in this report.
