2. Evolution (simplification)
~ kA
112 cm
230 cm
form relatively simple without reflector and with a lower current (and of course without degrading the physics performance!

3. 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 T2K)
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, AlBeMet?)

4. 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.

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

9. Safety (workshop at CERN next ~February)
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
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
