n_tofcollaboration ? • Infrastructure and experience • In 2011 new doctoral student • In 2011 application for new national funding - not big contribution - other applications - national, international • Work (hardware, software) and physics (PhD) topics?
Possible initial activities: • Neutron resolution function • Decreasing resolution of TAC • Diamond detectors
