9 CENF PTM - MC - Progresses on the SB facility
Integration update
30th May 2013
In order to move forward it would be necessary to proceed forward with a first engineering of the horn Upstream and downstream neck thickness important
input
Important input for target design, keeping the constraint of the physics requirement see next slide

Interface primary/secondary beam
NB: the collimator is there to protect the horn neck!
30th May 2013
14 CENF PTM - MC - Progresses on the SB facility
Interface primary/secondary beam
This solution is under investigation: DGS/RP
Evaluation of the iron/marble thickness required to guarantee access in the primary beam line for maintenance
Maximum aperture of shielding’s neck to minimize back-scatter
TE/VSC Technical feasibility of the proposed double-walled Be
window Important to clarify (primary beam):
Maximum angular spread of an off-axis beam in case of a magnet misfire
Beam divergence impact on collimator design, horn neck and DP exit window

Cooling and ventilation
Requirements from the SB under analysis by Michele B. https://edms.cern.ch/document/1288014
Comments: If possible use operational temperature >25 ˚C Several points are still to be estimated, but a starting point
to provide costs and surface requirements

Cooling and ventilation
Comments: As suggested by H. Vincke, use dry air for underground
ventilation circuits DGS/RP results for air activation will indicate the required
flush for the SP-VENT circuit input for DGS/SEE and EN/CV

Powering equipment for horn/reflector
The CNGS transformers have been recuperated from WANF S. Rangod (retired) and G. Marie (PH/DT/DI) responsible for
the electrical systems (transformers and pulse circuits) Shall we contact him to provide some feedbacks on the EL part?
30th May 2013
18 CENF PTM - MC - Progresses on the SB facility
Various items
1) In order to provide additional input, EN/EL will require a better understanding of the load distribution in the SB area
Will need input from EN/CV and a first integration implementation
2) Waste reutilisation under discussion with RP/RW
Possible use for the 2nd dump layer (reduction of muon fluence for EHN1)
Inside DP shielding concrete?
30th May 2013
19 CENF PTM - MC - Progresses on the SB facility
Various items
3) Discussions ongoing with EN/HE to proceed with the technical specifications of the main and of the auxiliary crane
Clarification of operation, redundancy, equipment on the hook, etc.
4) P. Ninin (GS/ASE) invited to participate to the SB WG activities as link person for the safety systems integration & related matters
