The major motivation of a Network Activity and
also R&D studies in this field is that the collection system
for the future neutrino beams will have to keep up with unprecendent challenging
conditions as such as 1) more than one order magnitude more electric stresses
(expressed in A.Hz) than the MiniBOON Horn and more than two orders
of magnitudes than the present K2K Horn and the future NuMI and CNGS Horns
and 2) a huge rapid neutron flux 10^22n/cm^2/6weeks due to the necessary
integration of the TARGET inside the COLLECTOR system. The NA will attack
the challenge by

The Institut will coordinate a consortium including physicists
from French CNRS and University Laboratories (IPN Lyon, LAL, LPNHE
Paris VI&VII) contributing long term expertise in the field of neutrino
PHYSICS,
experiments
& beams. It expects then to contribute to the
general steering
and provide technical expertise in the field of

design studies. (BETABEAM ???? )
Deliverables and relevant milestones:
COLLECTOR
The first deliverable for Summer 2004 will be a status report (R1)
on existing collection systems used in the past and currently in operation
(MiniBOON/K2K) and in construction (NuMI/CNGS). Then, till end 2006, studies
will be condcuted, to produce a detail report (R2) on a specific
solution for the SuperBeam project. Then, till the end of the NA Jan. 2008,
it is foreseen to produce a detail report (R3) on the different solutions
that will be avaliable for the Neutrino Factory project.
The 2 last reports (R2 and R3) will be based on
They will include proposition of specific solutions or R&D to be conducted necessary to achieve a lifetime of such system of few 100 Mega cycles or more. For instance, the documents will address solutions
- a detailed particle collection simulations (Monte Carlo based simulations with state-of-the art code: GEANT4, MARS,...),
- thermo-mechanical simulations that implies for instence to experimentally measure some relevant parameters (heat diffusion coefficients, stress limit under high neutron fluxes and after 10^8 cycles...),
- complete technical specifications of electric power supply and discharge equipment
- state-of -the art knowledge of mechanical properties of alloys under high rate neutron irradiation as already mentionned.
