Outline
• About this workpackage
• Focusing on the most challenging/crucial problems :
–

–
–
The target - talk by C. Densham
The collector
The target/collector integration
Neutrino beam simulation
• Participating institutes: IN2P3, CEA/IRFU(previously
Dapnia), CCLRC, Cracow U. of Technology
• Deliverables and milestones -> a CDR for the
Superbeam!

What Euroν DS Superbeam is about-1
• Consider as baseline the SPL to Frejus concept
MEMPHYS
Far detector feasibility, excavation,
engineering is covered by the Laguna DS

What Euroν DS Superbeam is about-2
• Proton driver and target : many issues in common
between Super-Beam and NF
• Decide to join forces and tackle these problems in this
WP
• The NF WP will focus on the muon front-end
• The conclusion of this WP will then be incorporated in
the SB and NF CDR’s

SPL
• Important and very positive recent news (see next slides
from R. Garoby and F. Gerigk)
• CDR for SPL available
• Ongoing work by dedicated team
• Refinements, R/D, further studies in other frameworks
(HIPPI, IA …)
• Changes to this proton-driver design only from the
optimization of the target and collection or from the
physics and detector studies

Collector
• Main challenges:
• design of a high current pulsed power supply (300
kA/100 μs/50 Hz),
• cooling system in order to maintain the integrity of
the horn despite of the heat amount generated by
the energy deposition of the secondary particles
provided by the impact of the primary proton beam
onto the target,
• definition of the radiation tolerance,
• integration of the target.

The power supply
Due to the high price go to a modular system and
increase small by small the current

Neutrino Beam simulation
• Needed to optimize the target, collector, decay tunnel
• Use modern tools (GEANT 4) and recent data (HARP)
• Input to the physics work package for the performance
evaluation
• Need to develop in synergy with similar studies in
existing SB and in the IDS community

Conclusions
• SuperBeam work package of the Euroν DS is focusing on
the key issues for this project
• The SPL to Fréjus project is the baseline
• Excellent news from SPL side
• Feasibility and conceptual solutions for the target and
collector (horn) will be studied
• A strong European collaboration is ready to contribute to
this field
