Evolution (simplification) 230 cm 112 cm ~300 -400 k. A 01/12/2010 M. Dracos form relatively simple without reflector and with a lower current (and of course without degrading the physics performance! 2

Base Line and option Separated target and horn • easy replacement of the target • cooling by gas He (probably not enough…) • supports have to be placed inside the hole of the horn to keep the target strait and well aligned • guiding system needed for the target insertion (à la T 2 K) • horn internal diameter relatively important (r~5+ cm) with physics effects Integrated target and horn • target replacement impossible • cooling of the target using water flowing inside the horn • current will pass through the target skin (r~1. 2 cm) • magnetic field very close to the target (better physics performance) • no need of target guiding system • the same material has to be used for the target and the horn inner cylinder (Beryllium, Al. Be. Met? ) 01/12/2010 M. Dracos 3

4 target/horn system • The target/horn system and the cooling system design will be done by Strasbourg • The 4 target/horn system assembling and study will be done by Cracow. 01/12/2010 M. Dracos 4

Costing of the facilities P. Bonnal “Project Cost Management – what is all about? ” What you have and what you don't have to cost… 01/12/2010 M. Dracos 8

Safety (workshop at CERN next ~February) q Identify safety issues in the project • Safety of personnel during installation, operation, maintenance and dismantling actions • Safety to materials/equipment – assure their operation as required by the specs • Impact to the environment during installation, operation and dismantling of the facility q Do risk analysis for each identified safety issue • Ways to mitigate the risk incorporate in the design, include in the cost estimate • Classify the risks setup the project risk register 01/12/2010 M.
