report

M. Calviani, P. Velten, A. Ferrari, I. Efthymiopoulos, C. Lazaridis (CERN)+ M. Zito, V. Galymov (CEA), A. Rubbia, S. Murphy, S. Di Luise (ETHZ)

LAGUNA/LBNO DS meeting / December 2012

2 M. Calviani -- LAGUNA/LBNO DS General Meeting

Organization of the WG and activities

Focused (for the moment) on: Agreement on the main physics parameters (ok now!) Optimization of beam/target optimization Configurations of horn Muons in the ND and configuration of the decay pipe

CERN-oriented meetings held on a ~monthly basis to discuss the activities within the sub-WG Steering the activities on the LAGUNA/LBNO

secondary beam line Participation to external members working on

some aspects of the beam line in other institutes Important input from the experiment!
