13. Second campaign of Geological survey
On last July the second campaign of geological prospection was completed at LNF site. 4 additional holes of different dept have been bored in the points reported below and marked by a blue arrow. Each hole was lined with a plastic pipe with an inner bore of about 70mm.

Bule= preliminary for WP, not good for TDR
Red= not done yet but planned for TDR

15. Road map since now till the day after approval
In order to not waste time, the day after the SuperB funding we should have the civil infrastructure preliminary design done!
DAY AFTER FUNDING
RADIOLOGICAL AUTHORIZATION FOR THE SUPERB OPERATION
CONFERENZA DEI SERVIZI
About 8-12 months to set it up
About 5÷6 years to get it

16. RADIOLOGICAL AUTHORIZATION FOR THE SUPERB OPERATION
It takes 5÷6 years to get this authorization. Without this authorization we can build the collider but we cannot run it.
What do we need to ask for it?
Collider design (Lattice, power, energy, particles lost, shielding calculation, positions for measurement of dose rate,… )
Civil infrastructure preliminary design

17. “CONFERENZA DEI SERVIZI”
The “conferenza dei servizi” setting up takes about 8÷12 months since the submission of the “preliminary design” of the civil infrastructure to the City Hall. Will last the entire period of design and construction.

18. BUT Since now to the SuperB approval and funding, we have to:
freeze the machine lattice and site soon (yesterday!!)
produce the civil infrastructures preliminary design
BUT
We do not have the human resources needed!
The only way, in my opinion, is to get external professionals.
How long does it take to have the preliminary civil design done?
About 5-6 months
How much does it cost? About K€

19. CONCLUSIONS
The footprint is the same presented at Elba last May. The Injection and transfer lines are also unchanged.
The white paper paragraph writing has been finalized. The preliminary design of the civil infrastructure should be done and added.
Few studies are still ongoing about the positioning of the tunnel and the various buildings and access pits.
A second campaign of geological prospection has been done (four additional holes) and results will be available in the coming weeks.
A new campaign of ground motion measurements is scheduled for the next 4th October with the collaboration of the LAPP group.

20. Access to the construction site
The access to the construction site or rather to the several concurrent site has to be optimized in order to prevent obstructions of the laboratory and site operations.

22. Cryogenic plant progresses
Dear Bill, Sandro and Giovanni
Please find attached my estimates of the required 4.5 refrigeration
capacity for the Babar solenoid and the final focus superconducting
magnets. These numbers are based on experience with BaBar and the
current conceptual design of the final focus magnet cryogenics. The
capacity numbers are conservative which is where we need to be at this
stage of the design. Based on the information from INFN, it looks as if
the existing Frascati Linde plant is significantly smaller than our
needs. The existing BaBar plant if operated at a flow rate of 150 g/s
nominally produces K. If we were to ship the plant I assume
we would also send along our helium compressors as well. The CTI plant
going to Fermilab is specifically being sent without that compressors to
make to allow them to be available for SuperB if needed. I hope this
helps. Please let me know if you have additional questions, comments or
suggestions on this topic.
Cheers, John Weisend

24. The second campaign of ground motion measurement was completed last October
For results see Benoit talk and LNF
See also IPAC’10 proceedings.

25. Electrical substation 150/20 kV 2 transformers 63 MVA each can be allocated (now 2*10 MVA)
R. Ricci

26. Cooling and HVAC (Heating, Ventilation and Air Conditioning) Plants
Gross estimation is:
- Thermal power: 30 Mw
- increase 20 % (inefficiency, contingency, etc.)
- actual power: 36 Mw
- tunnel length 2700m, tunnel volume m3
n. of sub-stations: 4
each substation requires:
- Covered technical room = 700 m2
- External technical room (cooling devices)= 1000 m2
