EUROnu is a European Commission funded FP7 Design Study investigating three possible options for a future high intensity neutrino oscillation facility in Europe. These options are a CERN to Frejus Super-Beam, a Neutrino Factory and a Beta Beam. The aims of the project are to undertake the crucial R&D on each of the accelerator facilities and determine their performance and relative cost, including the baseline detectors for each facility. A comparison will then be made and the results reported to the CERN Council as part of the CERN Strategy Review.

Funding: This project if funded by Department of Atomic Energy, Government of India.
An ISOL post accelerator type Rare Ion Beam (RIB) Facility is being developed at our centre. The RIBs will be produced by using light ion induced fusion evaporation and by using photo-fission reaction, using a 50 MeV 2mA SC electron linac that is being developed in collaboration with TRIUMF, Canada. The primary reaction products will be ionized using two-ion source charge breeder. The possibility of feeding the primary reaction products directly to an ECR ion source using multi-stage skimmer and gas jet transport technique is being explored at present. An extended rod type heavy ion RFQ, one buncher and three IH cavities have been successfully accelerated stable beams up to about 415 keV/u. Three more IH cavities will increase the energy to about 1.3 MeV/u and SC QWRs will augment the energy thereafter. In the next stage of development, an Advanced National Facility for Unstable & Rare Isotope Beams (ANURIB) has been envisaged. This green field project will deliver stable & RIBs from 1.5 keV/u to 100 MeV/u. This will have both ISOL type and PFS type facility. Neutron & positron beams based facilities will also be built around the e^- linac.

The initial part of Radioactive Ion Beam (RIB) transport channel of SPIRAL2 consists of 2.45 GHz ECR Ion Source, focusing solenoid, triplet of quadrupole lenses and 90-degrees analyzing bending magnet. The supporting gas (Nitrogen) current of ECRIS used in RIB production has a value about 1 mA. The influence of the Nitrogen beam self-fields may leads to hollow beam formation in the transported ion species at the part of beam line placed after the focusing solenoid. This effect increases the RIB emittance and therefore complicates the RIB transport. In this report the numerical simulation of hollow beam formation is fulfilled. The threshold current of ECRIS supporting gas which gives a hollow beam formation of transported ions is defined. The influence of the beam neutralization is taking into account. The possible neutralization factor is found from results of simulation of GANIL Test Bench. The simulation of a variant of quadrupoles focusing system of the initial part of RIB transport channel is performed. The influence of the Nitrogen beam space charge on transport of 120+ ions with energy of 60 keV is studied.
