14. 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 wuld 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

17. CONCLUSIONS
The footprint has been updated to the v12 release. Also the Injection and transfer lines have been updated according to the last physics calculations.
The white paper paragraph writing has been finalized.
Few studies are still ongoing about the positioning of the tunnel and the various buildings and access pits.
Thank you to the contributors for the great work done up to now.

18. Preliminary Geological survey
On September 14th the first campaign of geological test started at LNF site: 4 holes of different dept have been bored in the points reported below. Each hole was tubed with a plastic pipe with an inner bore of about 70mm.
The number of holes was minimized due to budget reasons
A second campaign of other four holes is foreseen soon
50m
40m
50m
30m

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

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

21. 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
